Comment (by robertwb):
There is currently a distinction between the is_Xxx methods and the is_Xxx
functions. For example, the is_Xxx functions determine if the given object
is a subclass of the right thing. The is_Xxx method determines whether or
not the object in question is (mathematically) of the given type. We
should keep the latter, and it should raise a NotImplementedError if it
cannot be decided.
I just noticed is_Field has been changed to call is_Field on its argument.
If we keep the top level functions (which some people may be more
comfortable with), perhaps this is what we should do for all of them.
