Note that the view was expressed at the London WG14 meeting (going through
a list of extensions considering what might be worth putting in C1x) that
statement expressions and typeof might be worth standardising. This does
not of course mean that anyone will produce a concrete proposal to add
appropriate words to the standard, or that such a proposal will be
accepted for C1x.
