[fpc-pascal] type helper default property

[Mattias Gaertner]

Hi,

For example:
type
  THelper = type helper for string
    function GetItems(Index: word): word;
    property Items[Index: word]: word read GetItems; default;
  end;

Delphi forbids this with "'default' directive not allowed in record
helper type".
FPC ignores it. Aka aString[1] has still the normal meaning.

Same for arrays, double, integers.

Is this an oversight, or has FPC some use for the default directive?
