I was trying to use a generic class TDictionary<T> with type T. This

When I specialize a class using this TDictionary with a type:
TSecurity = object

e.g. TNewDict = class(TDictionary<String, TSecurity>);
it raise a compiler complaining that my TSecurity type has no
operator = defined.
But when I try to add like this:
TSecurity = object
....
class operator = (constref aLeft, aRight: TSecurity ): Boolean;
//<---compiler Error: Procedure or Function expected
end;
Did you try creating an "old-fashioned" = operator ?
Something like
Operator = (l,r : TSecurity) z : boolean;
begin
// compare here
end;
Just tried.
It complained: Fatal: Syntax error, "IMPLEMENTATION" expected but
"identifier OPERATOR" found
