In natural language we do all the time: using a part to mean the whole, a 
whole to mean the part, or some part to mean a different part. The context 
of the utterance is then used to disambiguate. (There are some long words 
for these concepts, I forget them now).

It is not clear whether a formal language should try to emulate or avoid 
this feature of natural language. It is certainly aids compactness.
