Let's play Name That Extension!

[Stefan O'Rear]

A large number of the newer GHC extensions have no cabal name.  This
is a very bad situation because if Hugs/yhc/etc were to gain support
for (say) GADTs, it would not be possible to run cabal programs that
require them, since the way programs specify dependency is with
-fglasgow-exts.  Also, what is the protocol for requesting cabal
extension names?  I've many Cool Extension Ideas for my haskeell impl
project (nowhere near done).
