Comment:

 We've already agreed (unanimously, I think) to remove them from base
 (http://www.haskell.org/pipermail/libraries/2012-June/thread.html#17881)
 and they have already been removed in HEAD. Nothing else in base, or the
 rest of a GHC tree, depends on it, so there is no need for it to be in
 base. Additionally, we, as base maintainers, have not been maintaining
 this code (as evidenced by #3160 not being fixed for years), and having it
 in base means that it will take months (if not years) for any bug fixes
 that people do make to reach end users.

 If you, or anyone else, wants the old implementation then please feel free
 to put the old code in a standalone package on Hackage, which could be
 added to the HP if the HP also wants it. At this point, this would
 scarcely be any more effort than re-adding it to base. If no-one is
 willing to do this before GHC 7.8.1 is released (that's ''at least'' 2
 months away, and probably more) then it will surely never be done.
