Make pattern synonyms work with Template Haskell
Template Haskell has no support for pattern synonyms. This should be added.
Specifically:
- Create syntax in
Language.Haskell.TH.Syntax
and corresponding functions inLanguage.Haskell.TH.Lib
- Support in !DsMeta for desugaring pattern synonym quotations. See
rep_bind
. - Support in Convert for splicing in pattern synonyms.
- Support in !TcSplice for reifying pattern synonyms. See
reifyThing
.
