OK, but even if we reach consensus that the change is worthwhile (for me
it's not), it's still extremely important to make this a language extension
which must be explicitly declared. Otherwise there *will* be heavy breakage
through transitive dependencies, cabal not being able to find an install
plan, etc. As was already noted, not everybody is using the latest and
greatest GHC (often for a good reason).
So in a nutshell: -0.5 from me if it's a language extension, -1000 if it's
on by default.
