Suneet Tipirneni ef8281b695 [ty] add support for mapped union and intersection subscript loads (#18846) ... ## Summary Note this modifies the diagnostics a bit. Previously performing subscript access on something like `NotSubscriptable1 | NotSubscriptable2` would report the full type as not being subscriptable: ``` [non-subscriptable] "Cannot subscript object of type `NotSubscriptable1 | NotSubscriptable2` with no `__getitem__` method" ``` Now each erroneous constituent has a separate error: ``` [non-subscriptable] "Cannot subscript object of type `NotSubscriptable2` with no `__getitem__` method" [non-subscriptable] "Cannot subscript object of type `NotSubscriptable1` with no `__getitem__` method" ``` Closes https://github.com/astral-sh/ty/issues/625 ## Test Plan mdtest --------- Co-authored-by: Carl Meyer <carl@astral.sh>		2025-06-23 16:38:01 +00:00
