I'm unsure if I should write use <name of module> in two special cases.

Special Case 1:

I'm in module A. This needs a functionality of module B. But it also needs the functionality of modules B1 and B2. B1 and B2 are inheriting from B. Or in other words B is the base class of B1 and B2.

Now in module A:

use B; # not necessary because B1 and B2 are using B.
use B1;
use B2;

Shall I write use B; or not. What is your opinion?

Special Case 2:

Class A has an object of class B inside and of course uses its functionality. Class A is not creating the object B. The object B is created somewhere else and to class A is given the already created object of B. Because the object B is created outside of class A, I can assume that the Module B was loaded before somewhere else. And thus writing use B; in class A would not be necessary. Would you write use B; in class A?

What is your opinion? Thank you very much!
