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.
