 my first attempt to write a dependent typed language. It is inspired by Idris,
 Elaboration Zoo, pi-forall, and various tutorials.

 I've got no idea what I'm doing here. I worked off of Jesper Cockx "Elaborating Dependent (Co)pattern Matching", leaving out codata for now.

+- I need to do some erasure of values unused at runtime

 ## References
 
 "Unifiers as Equivalences" has unification with types.  Look into adapting some of that (or at least read/understand it).  Indexed types are mentioned here.
