Be careful not to misinterpret the results of these functions; only
:func:`isCallable` has any measure of reliability with instance objects.
For example:

Python 3 is expected to introduce abstract base classes for
collection types, so it should be possible to write, for example,
``isinstance(obj, collections.Mapping)`` and ``isinstance(obj,
collections.Sequence)``.
