F841 unpacked vars from function call not reported as unused

[sk-]

Summary

F841 is not reporting as unused unpacked values from function calls.

Below is some code showcasing the issue (playground):

def func(x):
    t1 = tuple([1, 2])
    a1, b1 = tuple([1, 2])

    t2 = (1, 2)
    a2, b2 = (1, 2)

In the code above a1 and b1 are not reported as unused, whereas a2 and b2 are correctly reported as unused.

Local variable `t1` is assigned to but never used (F841) [Ln 2, Col 5]
Local variable `t2` is assigned to but never used (F841) [Ln 5, Col 5]
Local variable `a2` is assigned to but never used (F841) [Ln 6, Col 5]
Local variable `b2` is assigned to but never used (F841) [Ln 6, Col 9]
