>Is there an easy way to test two multi_index containers for equality, c1 == c2?

c1 == c2 is defined to be equivalent to c1.get<0>()==c2.get<0>(), which
is defined if the first index of the container is of type ordered, sequenced or
random access; in all these cases the expression is in fact equivalent to

  c1.size()==c2.size()&&std::equal(c1.begin(),c1.end(),c2.begin());

Is this not what you had in mind?
