Later, in commit 8db9ad, you revert that change. Was that intentional? I'm also wondering about the functions `loop` and `shutdown`, which were exported in `base-4.6`, but aren't in `base-4.7` and higher. Was that intentional as well? In particular, I'm trying to figure out what to do about #5443, which uses all 3 of those functions. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7482#comment:8> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
