Wait, wait.
>From what I can see you just redefined a variable and no matter
what happened before "testScript" (".py" not allowed) always returns
"Changed". In the end in a template you've got a variable that renders to 
"Unchanged" string and a script which is going to return "Changed"
regardless of any namespace issues.

In fact the question is: will the script see the "ns['text']"  construct
or not ?

My current experience is - it will not.

If anybody knows more - please comment.
