I was wondering the same when I worked on that code a few weeks ago;
since the ufunc "return" void, I wonder how feasible it would be to
return an int instead for error messaging. Since the ufunc are not used
directly outside numpy, it should not break the API/ABI in any way ?

I think more generally it would be nice to have a common error system
for the pure C code, because it is a bit of a mess right now. But that
would be again a lot of work :)
