Similarly to #65090 this is very likely a combination of the recent changes in expansion order (#63248, #63867) and globs not fetching macro expanded names properly (#56593).

In this case, however, the fix may be to turn the "non-empty glob must import something" error into a lint, we have an issue about that - #62334.

triage: P-high

Based on @petrochenkov's comment, it sounds like we plan to fix this in some form, and hence I am marking this as P-high.

I'm not clear though on who is going to fix this and how -- I'm going to re-assign @petrochenkov (as well as @XiangQingW) -- but perhaps somebody could clarify exactly which steps they plan to take? Sounds like maybe fixing #62334 is the plan?

I'll spend some time to dive into the issue this weekend.

This already has an outstanding PR in #65539.
