triple<_T1, _T2, _T3> utility::make_triple	(	const _T1 &	__x,
		const _T2 &	__y,
		const _T3 &	__z
	)			[inline]

A convenience wrapper for creating a triple from three objects.

Parameters:

	x	The first object.
	y	The second object.
	z	The third object.

Returns:

A newly-constructed triple<> object of the appropriate type.

The standard requires that the objects be passed by reference-to-const, but LWG issue #181 says they should be passed by const value. We follow the LWG by default.
