Would anyone be interested in me adding an koenig lookup swap function
to boost? (I would say it belongs in boost.utility).
It would be a swap function that uses Koenig lookup to find the 'best'
swap funciton, falling back on std::swap like this:
template <class T>
void koenig_swap(T& left, T& right)
{
using std::swap;
swap(left,right);
}
Several boost libraries (multi array, compressed pair, graph,
optional, spirit) already use this technique, each time explicitly
with 'using std::swap' instead of abstracting it out.
