FastString environments (maps)

type FastStringEnv a = UniqFM a Source #

A non-deterministic set of FastStrings. See Note [Deterministic UniqFM] in UniqDFM for explanation why it's not deterministic and why it matters. Use DFastStringEnv if the set eventually gets converted into a list or folded over in a way where the order changes the generated code.
