Is there a egg for syntax-case macros in Chicken 4?
No, there isn't, unfortunately. I once tried to implement this
but it quickly gets very complicated. If you want to port

In one sense, this is good news!
The two main pieces of good news in Chicken 4 are built-in macros and
built-in modules.
A question: does the builtin syntax-rules accept the (... ...) syntax
that Dybvig's system does? My code has some macros that expand to
Further investigation shows that (according to the manual) Chicken 4
supports the superior method of srfi 46 (an extra parameter to
syntax-rules which binds an identifier as the ellipsis identifier.
Which led me to the second part of srfi 46, which allows parameters that
live *after* an ellipsis,
Thomas Bushnell BSG scripsit:
Any hope of that making it in? Is it just awaiting code to implement
it?
The Chicken community doesn't normally reject new code unless it breaks
old code, so such a patch would most likely be welcome.

Do you know if syntax-case support is in the works? Would you recommend I
stick with Chicken 3.x if I need it?
(I'm test-porting an internal tool from MZScheme to Chicken to see if I can
get some performance improvements, and we've taken the plunge with
syntax-case enough that I don't see

You are correct that the 'psyntax' port for Chicken is incomplete in

Thanks, Zbigniew. I indeed figured out the renaming of #!rest before
Chicken sees it. But I didn't think of the hack and I'll give it a try
soon. However, it is not a nice solution and my guess would be that the
syntax-case egg should have a build in exception for the #!key and #!rest
keywords, so

Folks,
Since I'm still having problems with syntax-case and rest arguments, I
have devised the following example which hopefully makes my problem clear:
(define-syntax test
(lambda (x)
(syntax-case x ()
((_ (name ...) body ...)
(syntax
(define (name ...)
body
Mark,
The #!rest syntax is supported directly by Chicken and it appears the
extra indirection involved in syntax-case is causing the #!rest
keyword to be renamed before Chicken sees it (as you've probably
surmised). I do not know an easy way to fix this offhand, although

Hi all,
having recently learned syntax-case, I experienced the
following problem: a syntax-case macro defined within
a module may not call a function from the same module,
i.e.

(define (f x) x)
(define-syntax mac1
(lambda (syn)

Your other message came through. I was able to compile syntax case on

Thank you for the suggestion.Running csc with -verbose (-v2) seems to stop with the message 'Pass canonicalised.' However, running 'chicken' manually does generate syntax-case.c and I was able to use it to install syntax-case. Verified with (require-extension syntax-case)
