#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 elaforge): Yeah, macros in general would need to store the original form and somehow get back to it for errors. I'm sure this has been thought about quite a bit over the decades and the devil is in that "somehow." I don't know anything about that previous work, so I'll leave it at that :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14963#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
