Comment(by simonpj):
OK so the situation seems to be:
* There is still a performance bug in the type checker
* It goes away if you don't use functional dependencies
If you feel like turning your example into a reproducible test case we can
follow it up; or we can just leave it since it's not now important for
you. It's up to you really. "Reproducible" doesn't necessarily mean
"small"; it just means a set of instructions that someone can follow, and
preferably no hard-to-install dependencies.
