→ in lambda expression

[drdo]

I get a parser error when using → in a lambda expression.

Can you provide more details on how to reproduce this? For me the following code worked as expected:

{-# LANGUAGE UnicodeSyntax #-}

foo :: Int → Int
foo = \x → x

bar = map (\x → x)

[drdo]

Hey, sorry for the much delayed response. Here's code that reproduces it:

{-# LANGUAGE UnicodeSyntax #-}

foo = do
  mapM_ (\x → print x) [1,2,3]

If you try to press tab when in the line after the mapM_, you'll get a "Parse error".

If anyone cares about fixing this then please own this ticket, otherwise closing next month.

@chrisdone I'd care to fix this bug but my Elisp is too weak :-(

(and btw, how does one "own" a ticket? I can't (re)assign this issue as I'm not authorized)

[chrisdone]

@hvr I've added you to the haskell-mode team, so you can re-assign/close and push directly.

@chrisdone ack & thx

I cannot reproduce this error when using emacs -Q and examples/init.el.

@dudebout that's because it doesn't occur with the "simple indentation" mode
