XXX Introduce two new flag bits that can be set in a PyMethodDef method
\item
It's now possible to define class and static methods for a C
descriptor, as used for the tp
_
methods slot of a type. These new flag
extension type by setting either the
\constant
{
METH
_
CLASS
}
or

exist in the same namespace as normal methods without having to use
tedious construction code to insert the new special method objects in
the type's tp
_
dict after PyType
_
Ready() has been called.
If METH
_
CLASS is specified, the method will represent a class method
like that returned by the classmethod() built-in.
If METH
_
STATIC is specified, the method will represent a static method
like that returned by the staticmethod() built-in.
These flags may not be used in the PyMethodDef table for modules since
these special method types are not meaningful in that case; a
ValueError will be raised if these flags are found in that context.
