devel/hs-th-expand-syns: import hs-th-expand-syns-0.4.12.0

Expands type synonyms in Template Haskell ASTs.

As of version 0.4.9.0, this library is a small shim on top of
the applySubstitution/resolveTypeSynonyms functions from th-abstraction, so
you may want to consider using th-abstraction instead.
