FlexibleInstances Re: ANNOUNCE: GHC 7.2.1 Release Candidate 1

[Christian Maeder]

Hi,

I've noticed that with ghc-7.2 many modules with
LANGUAGE TypeSynonymInstances
now also require FlexibleInstances

Two examples are in the HTTP package Network.TCP and
Network.BufferType

Was ghc-7.0 wrong about this, before?

Cheers Christian
