That bug is fixed, but this one is still present. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11328#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I tried to catch all the places where they might show up in user-facing output, but it's not at all surprising that I've missed some. I'll take a look. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11328#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I noticed that generated names (e.g. beginning with `$tc` or `$tr`) were turning up in the autocomplete after defining datatypes interactively, so I fixed that too. It's a tiny patch, so maybe worth backporting to 8.0.1? But the bug is fairly obscure, so not a disaster if that's too much trouble. the auto completion. I've not changed this; I think it's the correct behaviour. A `#label` is not an identifier, it's a separate syntactic form, and there's no obvious basis for auto-completing it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11328#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
