Andrew,
I agree. And I've found that after reading about how they are
actually implemented in Java, most of the *quirks* start to make
sense. So, in my opinion, if you do not count the decision not to
include generic typing into the VM, they are implemented quite
sensibly. Also, once I got used to their peculiarities, I stopped
having extra work about them, I'd say they even make me work
faster. For me nowadays the worst thing about using generic is
that occasionally I have to @suppressWarnings to get the compiler
to stop whining about something that will infallibly work. Besides
that, I'm happy.
As for Lachlan's problem, I remember once being in a similar
situation. When first trying to deal with defining generic
Comparators for sorting. I can't recall the details, but remember
not being able to tweak my code so it is functional in all legal
situations. I finally got it solved by rearranging <? super
Something>, <Something> and <? extends Something>. My point being,
it was my lack of detailed understanding of Java generics that was
the problem, not the generics per se.

Hello Guido;
Coming from the Objective-C mindset they do seem really rather
annoying, but I find after some months of playing with them that
they are actually helpful in order to know what is inside
otherwise unstructured collections. I have also, in implementing
generics, identified a couple of "invisible" bugs in some caching
code which was quite neat and this showed me how generics can
actually be helpful to identify problems too. So I've come to a
point where I think they're actually quite handy despite the
extra work they create.
cheers.
Maybe I'm just too spoiled from Objective-C.
