[gambit-list] c-lambda behaviour...

Hello!

In a simple example, I saw a weird or unexpected (from me) behaviour from the c-lambda function. Here is what I did:

(c-declare "#include <stdio.h>") ((c-lambda () void "printf("test: %d\n", 10);")

This worked just fine, but if I do:

(c-declare "#include <stdio.h>") ((c-lambda () void (string-append "printf("%d\n"," "10);"))

I get:

*** ERROR IN "/home/dave/temp/test.scm"@4.11 -- Third argument to 'c-lambda' must be a string

Why is that the c-lambda cannot or does not evaluate its arguments? Is this occuring because c-lambda is a macro?

I'd like it to evaluate my (string-append ...) because then, I could simplify the usage of the ffi with macros...

Thanks!
