#12701: Eta reduce type synonyms when possible -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: feature request | Status: new Priority: lowest | Milestone: Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: backpack Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I'm -1 on this change, as it is very easy for a user to specify that they want eta-reduction. With this change, partially applying a type synonym would sometimes work and sometimes not, in ways that are perhaps surprising to users. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12701#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
