Re: New feature proposal: Support C-code inline?

[Noah Lavine]

I just looked at the code. It's really cool! This looks like a way to
write modules that use C and Scheme together in such a way that the
code is all in one place. I think it could be much easier to read code
written this way than code in separate C and Scheme files.

What do other people think?
