Too much overhead, compared to what?

Ok. I thought that you told about checking in
   pragma Assert (not Has_Element (C2));
   pragma Assert (not M.Contains ("two"));

if you told about new checking inside of

   Replace_Element (C, -2);  -- dangling cursor

it is not "too much".

<< This is a false analogy, since the name of the operations are

and To_Address.  Nary an "unchecked" in site... >>

Isn't To_Pointer equivalent to Unchecked_Conversion from Address to
Access ?
