std::initializer_list fix

[gogu]

Remove the constness of the underlying array used by a std::initializer_list so that elements can be moved from it.

[Nicolas Lesser]

It's not that easy unfortunately. This has been already proposed, so you might want to look up any previous discussion.

The biggest against: It breaks ABI.

P0065 seems to be the most currently relevant "movable initializer list" proposal. Its author says that the reason why we still don't have movable initializer lists it that "the committee denies that the problem is significant." (source). This doesn't mean we should give up, but it does suggest that we might want to focus effort on showing why this would be useful rather than just coming up with more proposals.
