#15646: ghci takes super long time to find the type of large fractional number -------------------------------------+------------------------------------- Reporter: Johannkokos | Owner: | JulianLeviston Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHCi | Version: 8.4.3 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #5692 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): As discussed on IRC, try to get it compiling for now and then we can worry about where to put the functions. [https://github.com/JulianLeviston/ghc/pull/1/files#diff- 199051a796530164d94214a54aadd294R1216 In this line] you specify `mkRational`s module as `GHC.Real` so that's where it should be. When you do that your `dsLookupGlobalId` call should work. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:64 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
