If anyone is interested in how this works, I've found András Kovács' "Elaboration Zoo" to be a good tutorial: https://github.com/AndrasKovacs/elaboration-zoo It incrementally covers normalization by evaluation, bidirectional typechecking, basic pattern unification, implicit insertion (which relies on unification), and then more sophisticated variants on pattern unification. |
