* | Don't report fundep wanted/wanted errors | Simon Peyton Jones | 2017-04-06 | 1 | -0/+26 |
This makes GHC drop derived FunDep errors when they are come from wanted/wanted interactions. Much along the lines of "don't rewrite wanteds with wanteds". See TcRnTypes Note [Dropping derived constraints] and the new code in isDroppableDerivedLoc. Fixes Trac #13506. |
