:-) I guess it is time for someone to expose the existing machinery in
the compiler to the C language. All the semantics are already there.
All the backend code is already there. All the hard work has been
done. What remains is to invent a syntax and wire it up. Glue code
if you will.
If someone wants a cool project, and wants to be forever blamed for
exception handling in C, I'd even provide pointers, tricks and
details... Step on up, don't be shy.
