[fpc-pascal] How to declare function with untyped array parameter

[LacaK]

Hi,

is there way how to declare function, which will accept as parameter any 
array type ?
(this parameter I need forward to System.Length() only )

Just like Length() function.

Now I fall into problem with generics , where I have in one unit generic 
object, which has Length property (or Length function)
This function internally calls System.Length(A)

But when I specialize such generic in another unit, I give "Compilation 
aborted" (FPC 2.6.4)

Culprit is prefix "System.".

When I omit prefix "System." then I give another error: Wrong number of 
parameters specified for call to "Length"
(compiler is probably recognizing "Length" of object )

Example:

-----------------------------------------------------------------------------

1st unit:

   generic GT<T> = object
     private
       var
         FArray: array of T;
         Fx, Fy: integer;
       function GetLength: integer;
     public
       type
         TElement = T;
         PElement = ^T;
       constructor Init; overload;
       constructor Init(x,y: integer); overload;
       property Length: integer read GetLength;
   end;

function T2DArray.GetLength: integer;
begin
   Result := System.Length(FArray);   // <-- HERE prefix System is 
causing "Compilation aborted" in FPC 2.6.4
end;

-----------------------------------------------------------------------------

2nd unit:

T2DIntArray = object(specialize GT<Integer>) end;

-----------------------------------------------------------------------------

Is there any workaround ?

Thanks
