since their initial introduction.

PatternSynonyms was implemented in GHC 7.8, and TypeFamilyDependencies

I'm working on some code I want to be compatible with multiple GHC versions
and I'm trying to figure out which language extensions I can reasonably
use. I definitely need usable fancy pattern synonyms (not the bare-bones
ones in 7.8). So that should set a lower bound, but I don't remember where.
