I'm sorry, about the second case, don't you have to std::move(a), in order to
accomplish what you want? At, least, this is what we consistently do in the
experimental bits of the library.

The errors test2.cc generate vary if the various functions are commented out.

This is an old patch that purports to fix 3rd of the original tests.

So, let me understand, as in a previous PR of yours, the problem boils down to
intializer_lists only?
CC-ing Jason in any case, because of the ICE.

Also, there is the issue of lvalues binding to rvalue references. See N2831 and
possibly n2835.

I meant rvalue references binding to lvalues, of course.

The updated version n2844. From the intro: (I guess I meant being bound to in
the language of the standard)
int i = 2;
double d = i; // previously well-formed (d bound to a temporary double), now
ill-formed
--- Comment #15 from paolo dot carlini at oracle dot com 2009-04-27 16:32

Nope. The issue is the usual one: obviously d is an rvalue reference binding
the lvalue i.

Further consideration seems to indicate that the standard spuriously allows the
second case to be illegal.
