Description

IMHO, the biggest improvement to records in recent years was the addition of methods.
I suggest that possibility for developers to define methods for arrays could be added too to great adavantage, especially open arrays.

I can easily see the following be used in numerous units in my apps:

Type
      TMyArray : Array Of Integer
             Function Add : Integer;
             Procedure Clear;
      End;

Procedure TMyArray.Clear;
Begin
     SetLength(Self, 0);
End;

Function TMyArray.Add : Integer;
Begin
     ...
End;

Var
    MyArray : TMyArray;
    Index : Integer;
Begin
     MyArray.Clear;
     Index := MyArray.Add;
     MyArray[Index] := 1;
     ...
End;

Agree,
Another great improvement would be to introduce helpers for all types including integers, arrays, interfaces, floats, whatever you want, and not only for classes and records.

E.g.
TIntToStringHelper = class helper for integer
public
function ToString: string; inline;
end;

function TIntToStringHelper.ToString: string;
begin
result := IntToStr(self);
end;
