The procedure (when defined) will be called with seven arguments: a symbol indicating the analysis pass, the program database, the current node graph, a getter and a setter-procedure which can be used to access and manipulate the program database, which holds various information about the compiled program, a pass iteration count, and an analysis continuation flag. The getter procedure should be called with two arguments: a symbol representing the binding for which information should be retrieved, and a symbol that specifies the database-entry. The current value of the database entry will be returned or {{#f}}, if no such entry is available. The setter procedure is called with three arguments: the symbol and key and the new value. The pass iteration count currently is meaningful only for the 'opt pass. The analysis continuation flag will be {{#f}} for the last 'opt pass.

    100 ==== How can I specialize a generic function method to match instances of every class?
    101 
    102 Specializing a method on {{<object>}} doesn't work on primitive data objects like
    103 numbers, strings, etc. so for example
    104 
    105 <enscript highlight=scheme>
    106 (define-method (foo (x <my-class>)) ...)
    107 (define-method (foo (x <object>)) ...)
    108 (foo 123)
    109 </enscript>
    110 
    111 will signal an error, because to applicable method can be found. To specialize a method for primitive
    112 objects, use {{<top>}}:
    113 
    114 <enscript highlight=scheme>
    115 (define-method (foo (x <top>)) ...)

     133=== Why are `dynamic-wind' thunks not executed when a SRFI-18 thread signals an error?
     134
     135Here is what Marc Feeley, the author of [[http://srfi.schemers.org/srfi-18|SRFI-18]] has to
     136say about this subject:
     137
     138    >No the default exception handler shouldn't invoke the after
     139    > thunks of the current continuation.  That's because the
     140    > exception handler doesn't "continue" at the initial
     141    > continuation of that thread.  Here are the relevant words of
     142    > SRFI 18:
     143   
     144    >
     145    >  Moreover, in this dynamic environment the exception handler
     146    >  is bound to the "initial exception handler" which is a unary
     147    >  procedure which causes the (then) current thread to store in
     148    >  its end-exception field an "uncaught exception" object whose
     149    >  "reason" is the argument of the handler, abandon all mutexes
     150    >  it owns, and finally terminate.
     151    >
     152   
     153    >The rationale is that, when an uncaught exception occurs in a
     154    >thread the thread is in bad shape and things have gone
     155    >sufficiently wrong that there is no universally acceptable way to
     156    >continue execution.  Executing after thunks could require a
     157    >whole lot of processing that the thread is not in a shape to do.
     158    >So the safe thing is to terminate the thread.  If the programmer
     159    >knows how to recover from an exception, then he can capture the
     160    >continuation early on, and install an exception handler which
     161    >invokes the continuation.  When the continuation is invoked the
     162    >after thunks will execute.
