Partially qualified names

[Peter Alexander]

Suppose I have some long symbol name:

foo.bar.baz.quux;

I can refer to it as simply quux if the name is unambiguous, but 
when there is an ambiguity I have to refer to it by its full 
name, foo.bar.baz.quux, which can be frustrating for long names.

It would be nice if I could refer to it by partially qualifying 
the name, e.g. baz.quux or bar.baz.quux. Of course, the partial 
qualification itself would need to be unambiguous.

Is there any reason this couldn't be done, or should I file an 
enhancement request?
