Tries to guess which modules are used by *function*.
Returns a list of module names.
This function is used by :func:`find_modules` to parse modules used by a
function. You can use it to check that all modules used by your functions are
detected correctly.
The current heuristic requires that modules are accessed using the dot
notation directly, e.g. ``random.uniform(1, 10)``. For instance, required
modules are not detected correctly in the following snippet::
a = random
a.uniform(1, 10)
Also, modules used in generator expressions, like here::
return ((k, base64.encodestring(v)) for k, v in d.iteritems())
are not detected correctly.
