#10189: explicit promotions of prefix data constructors can't be parsed naturally -------------------------------------+------------------------------------- Reporter: Kinokkory | Owner: Kinokkory Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.8.4 (Parser) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | Blocking: Blocked By: | Differential Revisions: Related Tickets: #10188 | -------------------------------------+------------------------------------- Comment (by simonpj): Would it really be so bad to change it so that the tick goes inside the parens? It'll only affect people using (a) promotion, (b) type operators, and (c) prefix use of same. I'd prefer just to get it right. I think of `':` as the name of the promoted constructor, and if you want it prefix you should wrap it in parens.
