Everything else in Java eventually seems obvious.  Generics on the
other hand get weirder and weirder the more I learn.  I think it was a
mistake to try to do generics purely at compile time.  It is like
trying to do all types purely at compile time.

Have  we gone down that road too far now that Java can never be fixed
with run-time generics info without starting over with some completely
different notation? Then serialisation could work, containers could be
allocated with the precise array type.  You would not have so much
under-the-hood casting.

Perhaps it is time to read-read all the generics docs and see if they
make more sense now with some practical experience under my belt.
