Cello: Higher Level Programming in C (github.com)

Now this looks like an assortment of terrible hacks that I'd never want to use.

Good job though.

Very impressive! Especially the fact that it only uses macros (if I parse the website correctly).

I am currently working on a compiler that emits C and have been looking for something along these lines.

I'll definitely look into this!

for me this takes the fun out of C, however, it's pretty cool project full of neat tricks to learn form if you want to know what C can do or how to implement certain high level constructs in your own projects. good job!
