I've been meaning to port the stuff I have for my research thing to nbe-for-mltt.. I can probably just do that this evening

This sounds very interesting, if you have an example I’d love to see it

OK, the code is here github.com/jozefg/nbe-for. It will be merged into master once I finish documenting the new type checker

Thinks so much for this! Working on porting this to Rust so that I can figure out if I want to use it in Pikelet: github.com/brendanzab/rus - Still need to add a parser, pretty printing, and some tests! 🙂

Do you know if recursive definitions could be implemented using this style of semantic type checking? I'm considering going with an Idris approach to this - allow general recursion, but have a totality checker to ensure that a subset of the language terminates.
One must be a bit careful that everything is termination-checked before you attempt to normalize it (otherwise normalization might diverge) but if you do this (or are fine with things diverging) it should be fine. Mini-TT supports recursion IIRC

Currently trying to add the labelled sums from the Mini-TT paper to the language! Just curious, why do you need the type annotations in the values? They seem to manage without it in the Mini-TT paper. 🤔
