22 Containers library [containers]

22.3 Sequence containers [sequences]

22.3.9 Class template forward_list [forwardlist]

22.3.9.7 Erasure [forward.list.erasure]

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

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

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

Effects: Equivalent to: return c.remove_if(pred);
