Several advantages:

1) It is easier to maintain the code as origins of imported 
symbols become obvious immediately - less chance to get unused 
imports hanging around after some refactoring.

2) Considerably smaller chance of name clash between symbols from 
different modules (can only clash if used within same function / 
scope)

3) If it is templated function / scope, it won't be imported 
unless template is instantiated. "lazy" import effect. That may 
improve compilation times quite a lot in certain style of code.
