Status: RO
I'd rather see the current version of Icon released in 2 parts - an Ansi-C
compatible
source code tree that could be compiled directly using an Ansi C compiler, and
the rest (including the current co-routine switching mechanism) that would have
to be manually ported to any new system. This reorganization ought to make
porting
Icon to new platforms easier.
