The overload keyword was introduced in Delphi 5. We supported it already
for delphi compatibility. Since Delphi also does inherited overloading we
choose the best way to be both backwards compatible and delphi compatible.
When the overload keyword is not used then overloading works only in the
current scope. With the overload keyword the overloading will enable
global/inherited overloading.

With overload you can also overload cross units:

unit a;
procedure test(s:string);

unit b;
procedure test(i:longint);overload;

program c;
uses b;
begin
  test('string');
end.
