I'm also for an error.
However does Delphi pick a suitable non-generic overload if one
exists aside from the two generic ones?
Can you give an example what you mean?
I think sven means if you have e.g. 3 functions:
generic function DoThis<T>(a: T): T; overload;
begin end;
generic function DoThis<T,U>(a: T): U; overload;
begin end;
function DoThis(aInt : Integer) : Integer;
begin
end;
Should the compiler choose the 3rd non-generic function, or still give an
error ?
Michael.
