#14845: TypeInType, index GADT by constraint witness -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.5 Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #13895 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): OK. Then we can just reword the error message. :) Note that problem isn't that it's a GADT constructor. The problem is that it's a constrained constructor and constraints don't promote. Ryan, you find it far easier than I to actually get patches sent off -- would you mind tweaking this message?
