Hi all,
I met this problem when having some experiments with define-syntax.
Just cannot understand what I do wrong.
('a (display "Test:a\n"))
('b (display "Test:b\n"))
('c (display "Test:c\n"))
(_ (display "Unknown message\n")) ) ))))
(define t (test))
(t 'a)
This is a simplified part of the code. Executing this leads to following error
?: 1 (if (equal? args (quote a)) ((lambda () (display "Test:a
<unnamed port>: While evaluating arguments to equal? in _expression_ (equal? args (quote a)):
<unnamed port>: Unbound variable: args
ABORT: (unbound-variable)
with guile-1.8.7, and to
Throw to key `unbound-variable':
ERROR: In procedure module-lookup:
ERROR: Unbound variable: args
Entering the debugger. Type `bt' for a backtrace or `c' to continue.
with guile-1.9.11.
Does it mean I cannot use (match ...) within macro-definition?
Thanks!
