Hard to say. I hear all this hype about tagged types and I see a
few small examples of how they're used with packages/generics/...,
but has anyone implemented a few OO problems with each and compared
them? Semantically, it was easier to add extensiosn to Ada than a
class construct. But, I think the jury's still out on the "type
extensions > classes" question.
And, maybe it's not as much close minded as cost. Someone told me
to invest all this money up front on reusable class libraries. Now
you want me to switch to a non class-based language? Doubt it will
happen. People seem to use what they like and OO developers like a
class construct. Tagged types are not new and for some reason or
another were never embraced by the OO community. Should be an
interesting next fwew years.
