Those who think Java is a good idea are already discussing using
variants.

Um, C family languages were obsolete before their introduction. Von
Neumann thought that floating point was a bad idea, he was right then
and he's right now. If you're really interested in flexibility and
modularity, what possible attraction can a C-family language have? Even
with local classes Java is still not providing proper support for basuic
abstraction.
That sort of thing.
