This was suggested early on. Fundamentally, it's not much different than
Sean O'Dell's RCR, and I think that it's as fragile.
But your post does point out -- as does the existence of types.rb and
StrongTyping -- that this need not be in the core of Ruby. It also
demonstrates that even if it were in the core of Ruby, if it's not used,
it's about as useful as pinkies on a Penguin.
