I am a mathematician and a member of the "small is beautiful" crowd. And R5RS-Scheme is the definite example, that a small language is possible which allows one to do almost everything with it. And that in a clear syntax -- or should I better say -- with almost no syntax at all? And it is a programmable programming language! You can always add new syntax to it.

In my mind, Chicken is the best Scheme implementation. Its compiler compiles to C in the most ingenious way, it has the simplest interface to C, and it has a beautiful infrastructure, the eggs system, a helpful community and, and, and ...

== Eggs

=== [[/eggref/4/contracts|contracts]]

An implementation of "Design by Contract", coined by Bertrand Meyer for his Eiffel language.

=== [[/eggref/4/low-level-macros|low-level-macros]]

Low level macros made easy.
A merger of the two eggs er-macros and ir-macros, which are now obsolete.

=== [[/eggref/4/anaphora|anaphora]]

Anaphoric macros.

=== [[/eggref/4/loops|loops]]

Some simple loop macros.

=== [[/eggref/4/bindings|bindings]]

A light-weight alternative to the matchable egg, with many enhancements. Can destructure arbitrary mixtures of lists, pseudolists, vectors and strings.

=== [[/eggref/4/tuples|tuples]]

Something like immutable random-access vectors, with empty, couples and triples as special cases, and mutable singles as a possible replacement of boxes.

=== [[/eggref/4/skiplists|skiplists]]

An alternative to balanced search-trees.

=== [[/eggref/4/er-macros|er-macros]]

Explicit renaming macros made easy.

=== [[/eggref/4/ir-macros|ir-macros]]

Implicit renaming macros made even easier.
