I never said it didn't, did I?  Do I have to suggest again that
you get out some books on logic?

Yes, it's neat.  And yes, you *can* do it with other languages.  You
just need the framework.   As I stated before, Java's strength is in
the fact that much (most) of this is built-in, making it easier to use.

The you don't understand as much as you claim to.  Shared libraries
in and of themselves aren't, no.  But shared libraries with the
correct information in them are.  Which is what I said.

You are correct.  And so am I.  Why are we arguing?
