Bool_t PyROOT::Utility::AddBinaryOperator	(	PyObject *	left,
		PyObject *	right,
		const char *	op,
		const char *	label,
		const char *	alt = `NULL`
	)

Install the named operator (op) into the left object's class if such a function exists as a global overload; a label must be given if the operator is not in gC2POperatorMapping (i.e.

if it is ambiguous at the member level).
