Re: [GHC] #2915: Arity is smaller than need be

#2915: Arity is smaller than need be --------------------------------------------+------------------------------ Reporter: simonpj | Owner: simonpj Type: bug | Status: infoneeded Priority: lowest | Milestone: 7.6.2 Component: Compiler | Version: 6.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime performance bug | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Comment (by nomeata): Reading more code I found this change (a522c3b25eea1fe40edae7052335acce75e8a1c3) introduced in response to #5625, which prevents this eta-expansion to be pedantic about bottoms. The `-fpedantic-bottoms` check was added later. So I guess one could argue that if this flag is off, we should go back to the more liberal eta- expansion. I’ll try that and see what happens. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/2915#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
