I hear you. But as compiler writers we have a limited complexity budget and number of implementation cycles, and we need to think how best to spend them in the service of our users. Both in the initial cost of design and implementation and in the ongoing cost of maintenance. I think what you want is hard, so there's a risk of making the best be the enemy of the good.
Bgamari suggested a general mechanism like [[Design/LocalWarningPragmas]] that would certainly make `NO_WARN_REDUNDANT_CONSTRAINTS` unnecessary. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10635#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
