git head no longer builds with ghc < 7.10
Building git head after commit 4fffbc34 with ghc-7.8 or ghc-7.6 I get:
compiler/typecheck/TcInteract.hs:2034:13:
Not in scope: ‘<$>’
Perhaps you meant one of these:
‘TcM.<$>’ (imported from TcRnMonad),
‘<+>’ (imported from Outputable),
‘TcM.<*>’ (imported from TcRnMonad)
compiler/typecheck/TcInteract.hs:2034:29:
Not in scope: ‘<$>’
Perhaps you meant one of these:
‘TcM.<$>’ (imported from TcRnMonad),
‘<+>’ (imported from Outputable),
‘TcM.<*>’ (imported from TcRnMonad)
The <$>
operator is only available by default in ghc 7.10 and later.
