-- Note [Parsing sections]
-- ~~~~~~~~~~~~~~~~~~~~~~~
-- We include left and right sections here, which isn't
- -- technically right according to Haskell 98. For example
- -- (3 +, True) isn't legal
+ -- technically right according to the Haskell standard.
+ -- For example (3 +, True) isn't legal.
-- However, we want to parse bang patterns like
-- (!x, !y)
-- and it's convenient to do so here as a section
