Personally I’ve handled this by just ignoring the gradual part and keeping everything strictly typed. This sometimes requires some awkwardness, such as declaring a variable for an expression I would otherwise just write inline as part of another expression, because Pyright couldn’t infer the type and you need to declare a variable in order to explicitly specify a type. Still, I’ve been quite satisfied with the results. However, this is mostly in the context of new, small, mostly single-author Python codebases; I imagine it would be more annoying in other contexts.
