Please confirm typing of _tzinfos kwarg for typeshed

[angelaambroz]

👋 Hi! New contributor here. I'm updating the typing stubs for pytz in typeshed (PR#3393), specifically adding FixedOffset's typing. I'm unsure about the kwarg though, _tzinfos.

Here's the line I've put in typeshed. @stub42 Can you confirm the typing of _tzinfos (and, of course, let me know if the other types are wrong). The typeshed tests run, and it looks right to me... but I don't know pytz well enough. Thanks!

The _tzinfos parameter is private (per the old _ prefix naming convention), and only intended for use by the unpickler. The type is some horrible data structure as you have found (and which I don't recall), but better if you can flag it as some opaque type.

Thanks for the quick reply. Given that, I might just remove the kwarg from the stub altogether, which will just let typing evaluate it to Any; if it's a complicated data structure and it's meant to be private, easier to just let it be whatever it is (i.e. no explicit/static type evaluation). Otherwise, I'm not sure what "opaque type" to flag it to!
