Looking for std::map::erase_if

[Alan Somers]

It looks like it's in there.  What code are you trying that doesn't work?

> grep erase_if  /usr/include/c++/v1/map
  void erase_if(map<Key, T, Compare, Allocator>& c, Predicate pred);  //
C++20
  void erase_if(multimap<Key, T, Compare, Allocator>& c, Predicate pred);
 // C++20
void erase_if(map<_Key, _Tp, _Compare, _Allocator>& __c, _Predicate __pred)
{ __libcpp_erase_if_container(__c, __pred); }
void erase_if(multimap<_Key, _Tp, _Compare, _Allocator>& __c, _Predicate
__pred)
{ __libcpp_erase_if_container(__c, __pred); }
