long_long_
synopsisExposes a TypeWrapper for the Python long integer type.
long_Exposes the numeric type
protocol of Python's built-in long type. The semantics
of the constructors and member functions defined below can be fully
understood by reading the TypeWrapper concept
definition. Since long_ is publicly derived from object, the public object
interface applies to long_ instances as well.
