Hi,
I'm trying to use a syntax-case guard when the pattern has ellipsis.
So I have something like,
((_ (struct (k v) ...))
(string? (syntax->datum #'k))
exp)
And I want k to be a string. However, I am getting this error:
missing ellipsis in form (syntax k)
In ice-9/boot-9.scm:
106:20 0 (#<procedure 297a240 at ice-9/boot-9.scm:97:6 (thrown-k .
args)> # …)
For patterns without ellipsis it works great.
So, how do I make the guard when I have a pattern with ellipsis?
Thanks in advance,
Aleix
