Are you sure about the operator overloads? I'm pretty sure I've used
them on objects since FPC 1.0.x (even before that) and they've always
worked fine. They are also used by some of the PTCPas example programs,
which are shipped with FPC and also work fine. I even tested it again
with a trivial example. Here it is: It works with FPC 3.0.4 and almost
certainly FPC trunk as well:
type
TMyObject = object
end;
operator + (a, b: TMyObject) res: TMyObject;
begin
Writeln('Plus operator! yeah!');
end;
var
a, b, c: TMyObject;
begin
c := a + b;
end.
So, what's with all this FUD surrounding operator overloading not
working with objects? Did you even test it, before screaming "legacy!"? :)
