Which method is the fastest/best:

std::vector<int> foo1()
{
std::vector<int> v;
...
reutun v;
}

std::vector<int>& foo2()
{
static std::vector<int> v;
...
reutun v;
}

void foo3(std::vector<int>&v)
{
...
}

I tend to say foo3 is the best, however foo1 and foo2 are more
"convenient". Is there any way of returning a vector as fast as with
foo3?
