Hi,
Just looked at the latest version of C++0x draft (June) and I might
have spotted an error, not sure...
Shouldn't std::deque be MoveConstructible like std::vector? If you
insert elements in the middle of a deque then most of the
"reallocations" will be done with MoveAssign however the elements at
the end of the controlled sequence will need MoveConstruct surely?
Perhaps I am missing something, I am a concepts n00b.

Yes, std::deque should definitively be moveable, see the currently
active library issue
