23.3.9.6 Erasure [hive.erasure]

template<class T, class Allocator, class U = T>
  typename hive<T, Allocator>::size_type
    erase(hive<T, Allocator>& c, const U& value);

Effects: Equivalent to: return erase_if(c, [&](const auto& elem) -> bool { return elem == value; });

template<class T, class Allocator, class Predicate>
  typename hive<T, Allocator>::size_type
    erase_if(hive<T, Allocator>& c, Predicate pred);

Effects: Equivalent to: auto original_size = c.size(); for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; } } return original_size - c.size();
