#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: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by JulianLeviston): Hm... now, following the refactoring of changing the types, I'm up against this, in `Convert.hs`: {{{ cvtOverLit (RationalL r) = do { force r; return $ mkHsFractional (mkFractionalLit r) } }}} ... which clearly doesn't type-check anymore because it's expecting a `RationalL r` where `r :: Rational`. Given the `Lit` types for `TH` don't include anything remotely compatible with this, I'm not too sure what to do. Can we change `TH` syntax? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:36 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
