Not a big deal.

If we were before the release of tiger, we can:
- fix the Foo.class syntax to return Class<Foo<?>>
- fix object.getClass() to also returns a wildcard
- fix Enum.valueOf to take an Class<? extends T> instead of a Class<T>
- fix the compiler/spec because Enum<?> should be an <T extends Enum<T>> 
Enum<T>

so too many changes and most of them are incompatible with the current 
state of the language.

The only way I see to solve the problem now is to add a method in 
java.lang.Class
named getEnumConstant() that takes a String an return an Enum<?>.
