What Clem said, that is precisely how I feel. I'd be fully for them if they
fully type checked but without that, yeah, cpp is fine, enums are just a
distraction.

Amen bro. I always felt that they got added because
pascal had something
that C didn???t, and yet it really was not the same. I always felt they were
a feature that was only partly implemented and if they were not going to
be fully typed then just leave them out and use cpp like we had always done
before.

I hate enums. I thought they would be type
checked and they are just ints.
I love C but enums suck.

Sent from a handheld expect more typos than usual Another debate at the time was caused by a
disagreement between pcc and
cc
regarding enums: are they a type or just a way to
declare constant? I
remember getting annoyed by pcc not letting me declare a constant with an
enum and use it as an int. I protested to scj and dmr and after some
to-ing
and fro-ing Steve changed pcc to treat them as
constants.
Not sure it was the right decision, but C desperately wanted a non-macro
way to define a constant. I'd probably argue the same way today. The real
lesson is how propinquity affects progress.
