By hand, something approching could be:

template<class AssociativeContainer, class Predicate>
void erase_if(AssociativeContainer& cont,Predicate pred)
{
   //STATIC ASSERT that AssociativeContainer is not const
   typedef typename AssociativeContainer::iterator iterator;
   iterator it=cont.begin();
   const iterator end=cont.end();
   while(it!=end);

iterator tmp=it++;
         if(pred(*tmp))cont.erase(tmp);
