#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 goldfire): I actually proposed doing exactly that when working this out with Simon. The problem is that doing so would ruin error messages, because we could report errors only with respect to the expanded syntax, instead of what the user actually wrote. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14963#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
