#11835: ApplicativeDo failed to desugar last line with pure $ <expr> -------------------------------------+------------------------------------- Reporter: Cosmia | Owner: simonmar Type: bug | Status: merge Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1-rc2 Resolution: | Keywords: ApplicativeDo Operating System: MacOS X | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: #11607 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ezyang): Although it is terrible, I there is precedent for having a special case for `$` (letting it be impredicatively instantiated to handle things like `runST $ ...`). So I don't think it would be unreasonable for there to be a special case here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11835#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
