Nunchaku is a new higher-order counterexample generator based on a sequence
of transformations from polymorphic higher-order logic to first-order logic.
Unlike its predecessor Nitpick for Isabelle, it is designed as a stand-alone
tool, with frontends for various proof assistants. In this short paper, we
present some ideas to extend Nunchaku with partial support for dependent types
and type classes, to make frontends for Coq and other systems based on
dependent type theory more useful.Comment: In Proceedings HaTT 2016, arXiv:1606.0542
