Pyright's strict mode is becoming increasingly strict with regards to generics. You used to be able to effectively narrow them by declaring the type like so:
But that's no longer accepted. Now the actual value must itself resolve to something that has resolved parameterization. This unfortunately means that actual casting is sometimes necessary. It's not a huge hit because it's a do-nothing function, but it's still a function call that I'd rather not be doing.
