unification-fd: Simple generic unification algorithms. - Hackage
Generic functions for single-sorted first-order structural unification (think of programming in Prolog, or of the metavariables in type inference).
Unification (computer science) - Wikipedia
Type inference algorithms are typically based on unification, particularly Hindley-Milner type inference which is used by the functional languages Haskell and ML.
In this paper, we present an algorithm for dynamic pattern unification for a language with full-spectrum dependent types including - types. This algorithm is implemented in Haskell.1 Our …
