Cuse base has the potential to be very nice indeed. Preferably after pseudo hashes have been excised from the language. It happens at compile time. You can enforce various levels of stricture through it, which can potentially make it easier for the compiler to optimize stuff. It's vaguely necessary if you're going to have interfaces and all that (at least, the compile time behaviour is). I say keep it. Neither of these methods is the One True Way. They are both very useful in their place. Deciding where those places are is left as an exercise for the interested programmer. -- piers

I *do* agree with keeping @ISA, actually. :-) My message was spawned by a message of Ilya's proposing that we slash and burn everything except a very few variables. I actually said that this was a fragile approach. But I do agree new variables should be avoided where possible. Shit, 90% of my modules would break, including Class::Handler, which I particularly like (and there's no way around @ISA with 'use base', since it works at runtime). -Nate
