unbound-generics

Specify the binding structure of your data type with an expressive set of type combinators, and unbound-generics handles the rest! Automatically derives alpha-equivalence, free variable calculation, capture-avoiding substitution, and more. See Unbound.Generics.LocallyNameless to get started. This is an independent re-implementation of Unbound but using GHC.Generics instead of RepLib. See the accompanying README for some porting notes.
