I'll just reverse the change, which is easy to do. Two people have complained about the new behaviour and I don't think anyone complained about the old!
Please don't count me yet as complaining... but rather as wondering :-) The new error message hint {{{ Could not deduce (IsString [t]) arising from the literal ‘""’ }}} is provides some additional information the previous message didn't. The only downside of the new message is that it doesn't also give the hint of what an explicit type-sig would look like or that `FlexibleContexts` may let GHC continue) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10608#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
