Hi,
while syntax-case has some advantages, I was trying to implement a Chicken
style ir-macro-transformer in Racket so that I can write macros that will
run both on Racket and systems like Chicken/Chibi Scheme.
My first attempt was as follows:
(begin-for-syntax
(require (for-syntax racket/base))
(define-syntax (ir-macro-transformer stx)
(syntax-case stx ()
[(_ ir-trans)
#'(lambda (x)
#`(ir-trans #,(syntax->datum x) 23))])))
(define-syntax test
(ir-macro-transformer
(lambda (expr inject)
expr)))
The result was "Background expansion terminated abnormally (out of
memory)". If the #, is taken out I get an error that x is unbound. As
should be obvious from the above, I find it hard to reason about all those
syntax effects - which only makes me want the ir-macro-transformer more
despite all its shortcomings.
Any help would be highly appreciated.
