JEP: Extending generics to support primitive type arguments

[Paul Benedict]

Brian, what a puzzler! This might be the most complex proposed feature yet.
It will be a treat to see how others solve the problem.

Here is my first comment...
Given T=int, I would like to see the JVM magically substitute in an
"object" that's backed by the primitive. I use "object" in quotes because I
am not referring to something that's instantiated per primitive value --
but some sort of synthetic singleton where all int primitives point to the
same one. Since there is no other state in this "object" but the value
itself, this seems okay. The primitive value is actually the "this" pointer
in the virtual method call.




Cheers,
Paul
