0. Parsing. I wasn't actually able to find the code that parses pattern
synonyms. Can someone point me in the right direction?
Parser.y line 1356, production ‘patteron_synonym_decl’ looks plausible.
Currently we have
data HsPatSynDir id
= Unidirectional
| ImplicitBidirectional
| ExplicitBi
Never mind about parsing. It looks like the parser is already doing what it
needs to do and I need to look to RdrHsSyn.hs.
