The code is working on upp-mingw-11873,
This code is not supposed to compile with any compiler and latest version of Upp.
There are two issues with this code.
1. You are supposed to tell explicitly what you want to do with your Vector.
vvi.Add(clone(vi1));
vvi.Add(pick(vi2));
In the first case you are making a copy, in second - moving.
2. There is a problem with Vector& operator<<(const T& x)
It is supposed to look like below. This version of operator<< is missing.
Vector& operator<<(T&& x) { Add(pick(x)); return *this; }
In this case you would be able to write
vvi << pick(vi1) << pick(vi2);
Hope this helps.
Regards,
