[Numpy-discussion] cos -- NameError: global name 'cos' is not defined

[Wayne Watson]

I may have inadvertently made a slip between using script versus shell. 
What I'm getting at it that the namespace is the same for both the 
editor window and shell window. I find that a little bizarre. I would 
have expected each Run from the editor to clear all modules, and only 
load those shown in the editor.
