Richard Smith	5179eb7	2016-06-28 19:03:57	[diff] [blame]	740	<span id="p0136">(9): This is the resolution to a Defect Report, so is applied
				741	to all language versions supporting inheriting constructors.

				743	<span id="p0145">(10): Under the MS ABI, this feature is not fully implementable,
				744	because the calling convention requires that function parameters are destroyed
				745	from left to right in the callee. In order to guarantee that destruction order
				746	is reverse construction order, the operands of overloaded
				747	<tt>operator<<</tt>, <tt>operator>></tt>, <tt>operator->*</tt>,
				748	<tt>operator&&</tt>, <tt>operator\|\|</tt>, and <tt>operator,</tt>
				749	functions are evaluated right-to-left under the MS ABI when called using operator
				750	syntax, not left-to-right as P0145R3 requires.
