a module system for scheme [r6rs]

a module system for scheme (to be a part of R6RS) just came down as R6RS library syntax srfi 83.

The module system presented here is designed to let programmers share libraries, i.e., code that is intended to be incorporated into larger programs, and especially into programs that use library code from multiple sources. The module system supports macro definitions within modules, allows macro exports, and distinguishes the phases in which definitions and imports are needed.

i happen to think [as an implementor] this is about a decade too late; not having a standard module system drained scheme some of its early potential. [others would disagree and say scheme is a rare gem; its facets are slowly and carefully cut to brilliance. it is a fascinating way to build a language for an alternate universe.]
