Parametric Types?

Does ovld support parametric types like plum?

I would say yes, although I'm not 100% sure what you mean by parametric types.

• ovld supports list[int] etc. by checking the first element. AFAIK plum/beartype samples a random element (which I think is a bad idea in the context of dispatch).
• ovld also supports value-dependent types such as Literal["xyz"] or any type that customizes isinstance (see here). On these types, ovld has 10x less overhead than plum (see the calc, regexp and fib benchmarks).
