Nit, but this is what most other similar checks look like and I suspect mypyc handles it better. It's likely also faster in non-compiled Python to use a tuple here.

Not sure about mypyc, but for non-compiled Python it's actually a toss-up for two items. However, starting with three, sets are usually better.

I ran some local benchmarks and set is faster even for two-element tuples when the element is the second one. Still, better to be consistent with the other mypy code.
