Code Snippet

The ability to define a type alias using type Alias = tuple[int, int] was added in Python 3.12 so presumably Pylance needs to be updated to account for this new syntax.

Expected behavior

The type alias be syntax highlighted, not white, which is what you see when Pylance isn't working.

Actual behavior

The type alias be highlighted.
