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- and template-haskell- .
It seems I can upgrade to containers- and use it with no problems
but not alongside template-haskell: 

... changes: containers- ->,
Warning: The following packages are likely to be broken by the reinstalls:
... ghc-7.6.2

(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 has some advantages (like, speed) over
