HM

A simple, terminating, pure, hindley milner lambda calculus with inductively defined types.

For an example of the syntax see test.hm

Building

Depends: * BNFC * GHC * Cabal

Instructions: * Run cabal build

TODO

Currently there is no kind system and as such there are no indexed datatypes. Considering my interest currenlty lies in dependently typed systems this is not likely to change any time soon.
