Agreed. Everyone has their own list of things they want their language to do I
guess. Maybe I got spoiled with the typeless “id” type from Objective-C that
let me have little work arounds for things like this. Not having a dictionary
type after using PHP hurts also. ;)
Here’s another option I thought of. If the type casting was of a serious
quantity doing this could save time and improve readability of code.
unit unitA;
interface
type
class TClassA
private
FClassBObject: TObject;
public
procedure SomeProc;
end;
implementation
uses unitB;
type
TClassAHelper = class helper for TClassA
function aClassBObject: TClassB;
end;
function TClassAHelper.aClassBObject: TClassB;
begin
result := TClassB(FClassBObject)
end;
procedure TClassA.SomeProc;
begin
aClassBObject.OtherProc;
end;
end.
