----------------
@rsmith @david_stone (or anyone), what is the status in C++20 of the following
test case?
C&& test(C&& c) {
return c;
}
I know we talked about this in person at CppCon 2018, and concluded that our
//intention// was for this to be legal, but that it wasn't actually legal
as-worded, because the returned thingie here is not an object but rather a
reference, and therefore none of
[P1825's](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1825r0.html)
wording actually covers it. Is that still the case? Is there an open issue
about this? Is there any appetite for Clang to just go ahead and //make// this
legal? (The current patch does //not// make this legal.)
