But as this is just an error message, I think it’s fine. I’ll validate and push. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/5412#comment:10> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This name is returned by **dataTypeName**. I don't know how to get the name without Prelude prefix. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/5412#comment:8> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Note that SPJ made a more elaborate proposal in the ticket, namely printing the name of the type with the error message. Do you think you can update your ticket to print a message similar to what Simon proposed? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/5412#comment:6> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#7897: MakeTypeRep fingerprints be proper, robust fingerprints -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonmar): I'll point out that the package name contains the version, so in most cases the current scheme is safe. Of course this doesn't help for the main package, but if you're serializing data from a properly packaged library, it's fine. The other problem is that !TypeReps will be currently distinguished when it would be safe to equate them. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7897#comment:4> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
