It can't be overkill because with anything less it would not be possible to produce a unique name. For instance, a strong use of it would be in debugging, instrumentation, etc. Then again, I think that the C proposal has limitations in C too (this is not to put it down, I don't know how much more it could do). For instance, as I recall it, two static functions in different translation units would have the same name. As well, I know this gets queasyish, but I'm surprised there was no wording to the effect that whether it is available or not is unspecified. That is to say, it could start eating up a chunk of memory in some programs. Such "machinery" seems to have been a bold move for them. Surely C++ throws a few curves here too. - Greg -- Comeau Computing, 91-34 120th Street, Richmond Hill, NY, 11418-3214 Producers of Comeau C/C++ 4.2.38 -- New Release! We now do Windows too.
