mymap.addpath(path,"#00FF00") changes list

[GoogleCodeExporter]

I'm not sure if it an issue… i haven't noticed it before, but now it bothers

What steps will reproduce the problem?
1. path = [(37.429, -122.145),(37.428, -122.145),(37.427, -122.145),(37.427, 
-122.146),(37.427, -122.146)]
2. mymap.addpath(path,"#00FF00")
3. path
[(37.429, -122.145), (37.428, -122.145), (37.427, -122.145), (37.427, 
-122.146), (37.427, -122.146), '#00FF00']

What is the expected output? What do you see instead?
expected unchanged path[], because it is needed for other purposes.
