t | j S)a Returns true if name binding introduces new namespace.
If the name is used as the target of a function or class
statement, this will be true.
Note that a single name can be bound to multiple objects. If
is_namespace() is true, the name may also be bound to other
objects, like an int or list, that does not introduce a new
namespace.
