Imports in python are not solved correctly

[konradweiss]

In python when writing import json.encode, not only json.encode but also functions in json are reachable. This is not correctly implemented currently and the following code has unresolved references:

import json.encoder

a=json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
b=json.encoder.JSONEncoder().item_separator
c=str(1)

Here https://docs.python.org/3/reference/simple_stmts.html#the-import-statement the example shows how imports of nexted modules leads to their parent modules being imported as well, only what is bound in the local namespace is more restricted.
