I think it's rather understandable as-is, thanks. I'm going to look into
it, regtest again on my side, and so on. I'll let you know how it goes
and in case everything is ok, we can go ahead, as usual.

Two quick comments:
1- ALISING should be intended as ALIASING, right?
2- I have a rough list of algorithms which can internally exploit
efficient moves (courtesy of Howard Hinnant ;). I would guess the same
is true for our simulated move-semantics, as far as containers of
containers are concerned:
- remove
- unique (done!)
- rotate (done!)
- sort
- stable-sort
- heap-sort
- partition (done!)

Comments?

Thanks,
Paolo.
