Interesting! I will check that.

I perfectly agree with that the advantage of GC is that it frees you of
the burden of calling free, which is just awesome. Point is some tasks
(in my program) still need to be done in standard C, and not scheme. I'm
talking about things like setting up low-level OpenGL arrays, dealing
with byte endianess in RGBA structures, powering algorithms which are
currently coded in assembly and benefit from it, and so on. Some tasks
do require standard C and/or assembly. It might only be 5% of the total
program, but they still exist. BTW it's one of the reason Guile exists
for: allow coders to do "some things in C" and "some things in Scheme".

Have a nice day,

Christian.
