In time, we'll implement the Delphi syntax for this, for compatibility reasons:

type
    TMyFlexibleArray = array of Integer;

begin
   MyFlexibleArray := TMyFlexibleArray.Create(1, 2, 3 {...});
end;

procedure MyProc;

var
   A: array of Integer;
begin
   A := [1, 2, 3];
end;

No, Pascal states that variables are not initialized.

That means either null or undefined.
