[Fedora-suds-list] wsdl.py class Definitions method open_imports - why base = self.url ?

[Rod Montgomery]

Trying to understand the code, to work on Ticket #239: handling recursive imports in WSDL files

In file wsdl.py in class Definitions there is this method:

     def open_imports(self):
         """ Import the I{imported} WSDLs. """
         for imp in self.imports:
             base = self.url
             imp.load(self)

What use is the second line from the bottom?

The variable  base  is a local variable of the method, is it not?

For that matter, I don't find any references to any variable named  base  anywhere in wsdl.py, other than on that line.

I see no reason not to delete this line. If there is such a reason, what am I missing?
