You know I'm pretty lazy and i agree with you about class based containers, being more maintainable. (But I'm lazy and they are lower to write).

What i really like about generics is whomever managed to sneak in there the limited form of type bounds in methods:
public T whatever();

It's just beautiful that there is a compiler error when you try to
assign the result
SomethingNotComparableAndRandomAcess something = whatever();

Kev: So close to covariants! Gimme!
