[boost] Re: Perfect Forwarding (almost)

With Mojo you would do something like:

struct X : moveable<X> { X(X&); X(constant_ref<X>); X(rvalue_ref<X>); // move constructor };

And it would always move from rvalues.

Meaning that you could pass an X rvalue by-value to an X parameter without any deep copying?

The intrusive part was that to solve the whole "binding rvalues to const&" problem you needed to return some special wrapper type:

moved<X> f();

Oh, really? Too bad; I guess this isn't really much of an innovation then. -- Dave Abrahams Boost Consulting www.boost-consulting.com
