This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 112c. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
The structure of 12.2.3 [over.match.viable] paragraph 3 is of the form
X is better than Y if
condition 1, or, if not that,
condition 2, or, if not that,
It would be better to de-bullet this description, define the conditions, and then say, “X is better than Y if condition 1, condition 2, ...” This would also avoid the awkward “or, if not that,” phrasing.
Rationale (November, 2014):
CWG expressed a preference for the existing structure of this paragraph over the suggested rewrite. The change from “or, if not that,” to “otherwise” can be handled editorially, if desired.
