(define-syntax def
(syntax-rules ()
((def (name arg ... (opt-arg opt-value) ...) body ...)
(define (name arg ... #!optional (opt-arg opt-value) ...) body ...))))
Error: during expansion of (syntax-rules ...) - segment matching not
implemented: (arg ... (opt-arg opt-value) ...)
Will segment matching be coming to Chicken 4 soon? In the meantime is there
a workaround? A few core parts of my DSL are written with segment matching
macros and like the old saying "You don't know what you've got till it's
gone."
Also would this work, even if segment matching was implemented? I think
Chicken 4 wiped out my previous versions so I can't test it. Is there a
proper way to use #!optional, #!rest and the like, or equivalent functions
like opt-lambda <http://schemecookbook.org/Cookbook/IdiomOptionalArguments>?
All in all, I'm very impressed with the new Chicken. It's very easy to use
even for a beginning Schemer. Keep up the good work.
Thanks
Jack Trades
