jonsterling / TT-Reflection

An experimental type theory with scoped equality reflection, and non-arbitrary proof search. This is basically a pared down version of Andromeda/Brazil, but with untyped reduction and a more Nuprl-like feel. Computational content of proofs is got via a realizability-based extraction. (Note: substitution is unsafe here, not because of a problem with the theory, but because I didn't understand how Bound works sadly.)
