| * | Set GenSigCtxt for the argument part of tcSubType | Simon Peyton Jones | 2018-07-25 | 1 | -0/+11 |
| The reason for this change is described in TcUnify Note [Settting the argument context], and Trac #15438. The only effect is on error messages, where it stops GHC reporting an outright falsity (about the type signature for a function) when it finds an errors in a higher-rank situation. The testsuite changes in this patch illustrate the problem. | |||||
