Thank you David for the hint!
I re read the "An in-depth explanation" part of
http://stackoverflow.com/questions/3279543/what-is-the-copy-and-swap-idiom/3279550#3279550,
it's great ! I understood when and above all how the memory is cleaned.
About your multidimalgorithm, what would be the problem if it'd be changed
like this ? (to sum up: passing parameter by value to optimize)
It's a well-known but (in my impression) not-too-widely used idiom. And
IIRC it even has no drawbacks (which is sometimes hard to tell, C++
being so baroque and fragile that something that looks rather innocuous
can actually be an epic catastrophe).
