By default, each time testmod() finds a docstring to test, it
uses a copy of M's globals, so that running tests on a module
doesn't change the module's real globals, and so that one test in M
can't leave behind crumbs that accidentally allow another test to work. This means examples
can freely use any names defined at top-level in M, and names defined
earlier in the docstring being run.
You can force use of your own dict as the execution context by passing globs=your_dict
to testmod() instead. Presumably this would be a copy of M.__dict__
merged with the globals from other imported modules.
