#14963: ghci -fdefer-type-errors can't run IO action from another module -------------------------------------+------------------------------------- Reporter: elaforge | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.4.2 Component: GHCi | Version: 8.4.1 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 simonpj): PS: using `WpFun` would mean you could return a single `HsWrapper` to wrap around the bind function, rather than returning wrappers for the function, the arguments, and the result. See its use in `TcUnify.tc_sub_type_ds`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14963#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
