#14076: cons operator for list give weird output -------------------------------------+------------------------------------- Reporter: AshHash | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: GHCi | Version: 8.2.1 Resolution: invalid | Keywords: cons(:) Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by goldfire): * status: new => closed * resolution: => invalid Comment: This looks like correct behavior to me. Recall that numbers in Haskell are overloaded, meaning that the type of a number `1` is `Num a => a`. Your initial expression conses one number onto another -- thus both the element and the list type must be in the `Num` type class. Please reopen if you see a flaw here somewhere, and thanks for posting! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14076#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
