should be short in usage. They exist for clear and reusable constructions.
I need to cite you: "Prefixed modifiers are the /worst/ you can do for
Pascal.". By introducing "specialize" keyword, you deny yourself.

I should have written this in the other thread where you mentioned this,
but I forgot, so: I agree that "specialize" falls into the same "prefixed
modifiers are the worst" category. The cleanest way for specializations
would be something like "TMyGeneric with (Longint, String)" or so, this way
there would be no potential disambiguity.
Nevertheless "specialize" had been introduced before my time, so I'm merely
working with what already /is/ part of the Free Pascal dialect (generics
were first introduced in 2.2 and I started working on the compiler with
That said: I /am/ working on Delphi compatible generics (in fact 3.0 is a
big improvement compared to 2.6 in that regard, but it's still quite a way
to go) and thus you /will/ be able to work with them in mode Delphi. So
just use that mode and be happy.
