A rose by any other name > *should* smell as sweet. >=20 Having programmed in Pascal, where you use the function's name as the return value pseudo-variable, I agree with that - it is a pain. It may also be a challenge for recursive functions, and it will certainly be a problem if you want to use the function more than once before checking for errors: x =3D foo(y) + foo(z); if (foo.error) ... // Which foo call? I appreciate the desire for cheap and standardised error handling, but this syntax is not going to work. --=20 You received this message because you are subscribed to the Google Groups "= ISO C++ Standard - Future Proposals" group.
