Yes, this is exactly right. Thank you Bjorn. The reason is that I cannot define a generic assignment operator because the assignment operator is required
to be a member function. If you provide your own assignment operator that is generic you can call the boost::polygon::assign from within it, but you would want to add the same SFINAE guards to it that I use on the definition of assign() to make it concept
type safe.

You could try:
boost::polygon::assign(p3, p1&p2);
Or, if you're using namespace boost::polygon::operators, you could write:
p3 = p1;
