May I ask where the syntax for “specialize” came from? Delphi doesn’t use it nor does any other language out there. Honestly it’s extremely verbose and makes me want to avoid generics sometimes. I just don’t get it. I will say that I like the “generic” addition to type declarations though because it makes it more clear what they are.
