:mrdocs:

Return `true` if the specified `lhs` iterator points to the same element in the same block as the specified `rhs` iterator, and `false` otherwise. The behavior is undefined unless `lhs` and `rhs` are iterators over the same deque. Note that this friend is a regular functon, not a function template, so there is no way to declare it outside the class in order to provide the definition.
