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. 7.10? 8.0? I'd also *like* to use an injective type family, but I can work around that pretty easily with a data family if necessary. When did PatternSynonyms and TypeFamilyDependencies each become reasonably usable? _______________________________________________ Glasgow-haskell-users mailing list [email protected] http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users
