Dropping support for NHC98 and old GHC from containers
The containers package currently includes CPP and Cabal directives intended to support NHC98 and versions of GHC before 7.0. However, our TravisCI script tests only GHC versions 7.0 and above. It is therefore likely that the compatibility code is bit-rotted to some extent. Wren Romano and I are strongly inclined to immediately remove all code intended to support NHC98 or pre-7.0 GHC. If anyone uses any such implementations with the current version of containers, please speak now or forever hold your peace. Thanks, David Feuer
Do it! :)

We did a similar cleanup pass on base a year or two back.
No objection here.
Code you can't test is kinda hard to maintain forever.

If base is not compatible with nhc98 anymore, there's a little point to preserve such compatibility on containers. Still, for less fortunate operative systems, it would be nice to have somewhere a list of modules/version actually compatible with Haskell 98. Also, for future reference, it would be nice if such change is introduced as a single-change version, so that we know it doesn't introduce or remove any other functionality except the compatibility.

I wonder what can prevent code to be tested with a different compiler... Giacomo
