Well, I am. When looking at someone else's code, it's
very useful to be able to take a name used in one source
file and easily find the file where it's defined. That's
very easy to do in Python, and very hard to do in languages
that don't relate namespaces and source files.

The experiences I base this on aren't confined to Python.
This is one of the very few things that I think Java got
right, and some of the other JVM-based languages -- such
as Scala -- got wrong.
