imp.reload() was deprecated in Python 3.4 and changed to call
importlib.reload().
Patch by Petr Viktorin.
Beware though, as if you keep a reference to the module object,
invalidate its cache entry in :data:`sys.modules`, and then re-import the
named module, the two module objects will *not* be the same. By contrast,
-:func:`imp.reload` will reuse the *same* module object, and simply
+:func:`importlib.reload` will reuse the *same* module object, and simply
reinitialise the module contents by rerunning the module's code.
