Is it still the case that
"It just doesn't work to have multiple versions of a wired-in package"
(cf. http://hackage.haskell.org/trac/ghc/ticket/5704 )?
ghc-7.6.2 comes with containers-0.5.0.0 and template-haskell-18.104.22.168 .
It seems I can upgrade to containers-0.5.2.1 and use it with no problems
but not alongside template-haskell:
... changes: containers-0.5.0.0 -> 0.5.2.1,
Warning: The following packages are likely to be broken by the reinstalls:
(Isn't it somewhat bold of cabal-install to offer to break "ghc-7.6.2"?
like, this will completely hose the compiler?)
That's bad, because I use containers everywhere, and I assume that
0.5.2.1 has some advantages (like, speed) over 0.5.0.0.
