Steps to Reproduce:

The code below produces an error in XE2.  It used to work with earlier Delphi versions.  The new Format function should try and cast the variant to the required type.   This is a problem with custom variants as well.

procedure TForm2.Button3Click(Sender: TObject);
Var
  V : Variant;
begin
  V := 3;
  ShowMessage(Format('%s', [V]));
end;
