Java is JIT compiled and function that aren't overriden are 
finalized automatically by the JIT compiler.

It's even able to virtualize at runtime if an override is finally 
linked, or the other way around, refinalize.

We could do that in D as LTO, as long as we have a way to tell 
the compiler if a function can be overriden in a shared object.
