Hi!
is it possible to make += also work for containers on right side? i.e. int a; std::vector<int> b; std::list<int> c; std::vector<int> d; d += a,b,c,d;
I would rather not have such a functionality, at least not without extra spelling around it. At a very minimum I'd expect some kind of d += a,expand_range(b),expand_range(c); or d += a,expand_ranges(b,c); or d += flatten(a,b,c); What if you have code that relies on an implicit conversion from those container types to the element type of the left hand side. You would suddenly and silently change the semantics of such code. Beware changes of semantics, because you _will_ have people that wittingly or unwittingly rely on them. -- Lars Viklund | zao@acc.umu.se
