#13876: Check 'pure' method of 'Applicative (WrappedMonad m)' -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: 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 RyanGlScott): It's useful since you often want to define `(<*>)` in terms of `(>>=)`. I'm putting this in a distinct category of retrofitted things from defining `return` from `pure`, since the latter is completely trivial (`return = pure`), whereas the former requires a tad more work. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13876#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
