Right, and the usual answer is that _if_ you want non-local
transfer of control, then checking error codes just won't do.
You'd be using something like setjmp/longjmp in C.
the alternative is to handle error codes all the way up the
call chain. The resulting code is more spaghetti-like and it
will mix both return values and special return values in
the same syntactic structure.

I can't think of a language in use today that does not have
either exception handling, or else some way to check, at compile
time, that none can occur.
