Fully agree. Even Java doesn't "objectify" arrays as some type of
object. Hence Java includes the Arrays class that has a static m

Yes but programmers tend to be neurotic and obsessive. :) I think many of us
would appreciate a matching "Count" met

they added these for dynamic arrays. I agree that dynamic arrays shoul

Hi,
I am trying to write some generic routines for working with containers. For
example, GetLength function:
unit u;
{$MODE FPC}
{$MODESWITCH DEFAULTPARAMETERS}
{$MODESWITCH OUT}
{$MODESWITCH RESULT}
interface
generic function GetLength(const V: TContainter): SizeUInt;
