I think we should apply both my pkg-config patch as well as this patch,
which fixes the RETVAL situation, and adds a macro for checking the
version exp
Hi y'all,
Is there any sensible way to implement the following semantics:
(+ (values 1 2))
==>
3
Or perhaps with a macro of some sort (but preferably as above)...
(+ (values->list-elements (values 1 2)))
==>
3
The intermediate step (after the macro expansion I guess) would look like
(+ 1 2)

Hi,
I'm new to this mailing list and also new to the scheme language ...
I'm used to Lua but I try to search about functionnal programming, and
