I don't get this crash with a Cygwin terminal, but rather see `??.hs`. I came across this because I was getting the same exception in the Cryptol REPL, so I suspect it's not unique to GHCi, but is rather something fishy in base. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10477> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #10145: :info (->) should list its fixity

#10145: :info (->) should list its fixity -------------------------------------+------------------------------------- Reporter: oerjan | Owner: Type: bug | Status: new Priority: low | Milestone: Component: GHCi | Version: 7.8.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Documentation Unknown/Multiple | bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- The GHC manual states: > * Function arrow is `infixr` with fixity 0. (This might change; I'm not sure what it should be.) Since this isn't the default `infixl 9`, it should be listed when you do `:info (->)`, but currently (at least in 7.8.3) isn't.

In that case we don't know which is the cause of the difference, right?
