from copy import deepcopy fails

[Skaperen]

if i were to do "from copy import foo" and still had that copy.py file which has no name "foo" in it, the import will fail and i would get the message "ImportError: cannot import name foo" because "foo" is not there in my "copy" module. python looks in my home directory first when it looks for files to import. it's a feature: that let's me substitute my own modules. then if i do that, all the same features like importing individual functions and data variables still work ... in my module ... including the error messages.
