1TODO for chicken                                                        -*- Outline -*-
5* bugs
7** compiler
8*** pre-optimization
9**** changes call-sites and makes them invalid for later pre-optimization
10*** check profiling (-profile vs. profile-declaration)
11**** this doesn't always seem to work, in particular with library units
12**** ##sys#finish-profile should always be invoked
13     is it in `exit'?
14*** when re-defining intrinsics, the compiler should warn and disable re-writes
15    add declaration to keep re-writes enabled for core library files
16*** check in foreign.import.scm and compiler.import.scm whether the import
17    took place in the compiler
18*** -prologue, -epilogue, -prelude, -postlude should check for argument being directory
19    (reported by Eduardo Cavazos)
21** expander
22*** expansion of r5rs_pitfall 4.2 incorrect
23    possibly due to a non-aliased implicit "begin" somewhere
24*** dirty-macros.scm loops when using `defile'
25    possibly due to unrenamed special forms
26*** extended lambda-lists refer to `optional' and `let-optionals[*]'
27    this will break, when these macros are renamed on import or not imported
28    at all
29**** a possible solution is to use internal forms, provided by the "scheme" module.
30*** need way to force generating module-registration code for standalone executables.
32** modules
33*** `require-extension' fails in interpreter when extension is .so without import library
34    probably because load and import is in same toplevel form, and the
35    load is performed after the import (at runtime). A possibly fix
36    would be to load the extension immediately (at
37    compile-/expansion-time), when import is #t and o import lib
38    exists.
39*** mark import-source (module) on plist of imported symbols and use in re-import warning
40    doesn't work that easily, try to find another solution
41*** DSSSL lambda-lists need imports of `chicken' module ("optional", "let-optionals", ...)
42**** should probably use internal aliases
44** libraries
45*** library/runtime: cyclic list checks for assq/assv/assoc/memq/memv/member
46    and C_i_list_tail
47*** finalizers on lexically ref'd data not working in interpreter
48    reported by Jim Ursetto
49    reverted original patch, see patches/finalizer-closures.diff
51** tools
52*** chicken-bug: SMTP servers not accessible
54** build
55*** somehow get SONAME to work
56*** integrate and build/install chicken-base.scm
58** tests
59*** should run without installation
61** setting nursery default size doesn't seem to work properly (reported by Zbigniew)
64* tasks
66** branches
67*** try to improve performance in lazy-gensyms
69** module issues
70*** need a way to omit generating module registration without generating import lib
71    for example when compiling static version, where implib already exists
72*** code-duplication in compiler and evaluator for ##core#module
73*** "scheme" module does not include some special forms ("define-syntax", etc.)
74*** import-for-syntax imports value bindings into import-env
75    should actually be a distinct meta-import-env.
76    example: we need `(import-for-syntax chicken)' to have access to
77    `receive' in a procedural syntax definition.
78*** curried define performs expansion in empty se - problem?
79    (as comment in expand.scm indicated (##sys#register-export))
80*** check phase separation and module access
81**** see "expander" above
83** compiler
84*** (csc) generate object-files in /tmp (or TMPDIR)?
86** setup/install
87*** setup-download
88**** use "HTTP_PROXY"/"http_proxy" env. var
89**** handle redirects in http-fetch
90**** option in chicken-install to list available eggs
92** library units
93*** read-mark list should be stored in read-table
94*** ports should have indicator slot about exact type (tcp, file, ...)
95*** normalize-pathname: return short name on windows? (mingw/msvc)
96*** Use record-descriptors instead of symbols as 1st slot in structure objects?
97**** see Kon's proposal for new record-descriptors in "misc/Chicken Runtime Data Type Proposal"
99** syntax-error
100*** if ##sys#current-module is set, add name to error message?
101*** fluidly keep track of expanded forms (extend meaning of culprit) to pprint pruned expr on error
103** build
104*** need script to process import libraries for generating indices for
105    then tell Toby Butzon about it
106*** test DESTDIR and proper linking
107*** using "touch" with WINDOWS_SHELL won't work (need alternative)
108*** extend scripts/ for more platforms
110** documentation
111*** document qs, normalize-pathname
113** scrutiny
114*** allow giving toplevel procedure names to `scrutinize' option?
115*** write test file to trigger every type of warning (diff with result file in test-suite)
116*** add support for keyword arguments and check even length and available keywords
119* wiki
121** compatibility page
124* extensions
126** check status of `s48-modules'
129* tests
131** optional longer run (env. var)
132*** syntax-rules-stress-test
133*** fully compiled ec-tests
134** 3-stage bootstrap with compiler-output comparison
137* optimizations
139** self-recursion optimization
140   what MacScheme called "benchmark-mode" (assume self-calls are recursion)
141*** needs declaration or option, >= -O2
143** when inlining, consing arg-list with "list" may make get-keyword possible foldable
145** compiler-support for get-keyword ?
147** lambda-fusion / "fuse-and-dispatch" (suggested by Alex Shinn)
148   convert groups of local lambdas referenced to only in operator-position into
149   looping lambda + dispatch (static variable can be used), otherwise similar to
150   a conditional
152** lazy gensyms (see "lazy-gensyms" branch)
154** handle optional args primitively
155   for example, set to distinguished val (checking argc) on C level, core
156   primitive for checking this - should be quite simple, but llist processing
157   (decompose-lambda-list) will be more expensive and cumbersome.
159** pre-hashed symbols (extra symbol slot)
160   The memory usage should be acceptable, performance gain is hard to guess.
161   Some experiments indicate that hashing the string is cheaper than it appears,
162   but low-level hashtables should get the most of this (and thus speed up
163   the compiler)
165** Lisp2-hack by Dybvig
166*** add function-cell to symbol, call on direct call without checks
167*** initialized to trap function on set!/define, which does fixup
168*** would also allow inline-caching hacks
