Python import alias

[Isaac0616]

Describe the bug
Not sure whether it is a bug, intended behavior, or should be a feature request.
For the pattern import $X.function, $X will only match one level of modules.
For example, it matches import x.function but not import x.y.function.
In contrast, for the pattern $X.function(...), $X would match multiple level of modules.
For example,

from x.y import function
import x.y.function

x.y.function()
function()

#1771 seems to be a relevant ticket.

To Reproduce
https://semgrep.dev/s/yz3A

Expected behavior
A way to match any level of modules.

Thanks for filing this issue! There has definitely been discussion about "import $X.function" matching cases such as "from x.y import function", and we agree that this makes sense. Another relevant ticket comment is #975 (comment). This would be a nice feature to have, although it's not currently high priority.
