std::pair and move-only types in C++0x ?

[SG]

Just a quick question:

Are std:air and std::tuple (C++0x) supposed to support move-only
types?

It sure looks like they don't judging by N3126.pdf. But I can hardly
believe this. I was expecting to be able to put a std::unique_ptr into
a std::map as mapped type.

If I recall correctly someone's working on a refined pair/tuple
specification to fix some other errors in the current proposal. It
would be great to hear from that someone or anybody else involved.

TIA,
Sebastian
