Tiny bug in lexer around lexing banana brackets
If I say
{-# LANGUAGE Arrows #-}
(|:) :: Int -> Int -> Int
(|:) = (+)I get
/Users/rae/temp/Bug.hs:3:3: parse error on input ‘:’Trying this with other operators, like (|+), works fine.
The problem is that notFollowedBySymbol in Lexer.x is slightly wrong.
I will fix in ongoing (mostly unrelated) work.
