#7454: Missing warning about redundant import of classes/types whose members are
used

-----------------------------+----------------------------------------------
If one module exports a class C(..) with a method m,
and another module imports it via: import Module(C, m)
And then proceeds to use only "m", one would expect to get a warning about
the redundant import of "C", but that does not occur.
Similarly, the same thing happens if one imports a data-type "D", and a
record field "f", and uses only "f". No redundant import warning is issued
on D.
