Slightly surprised that there was no TODO here. This looks fine?

The implementation here now follows map_with_boundness just above. It was wrong before (see test change in callable.md).

I think I prefer what we have in terms of readability. Not sure if it compiles to worse code (probably not?), but this is not a hot code path anyway.

…tions (astral-sh#20114) ## Summary Properly preserve type qualifiers when accessing attributes on unions and intersections. This is a prerequisite for astral-sh#19579. Also fix a completely wrong implementation of `map_with_boundness_and_qualifiers`. It now closely follows `map_with_boundness` (just above). ## Test Plan I thought about it, but didn't find any easy way to test this. This only affected `Type::member`. Things like validation of attribute writes (where type qualifiers like `ClassVar` and `Final` are important) were already handling things correctly.
