Hello,

with this article I want to bring two of my discussions together.

On one side I am avocating garbage collection and one argument against it is
that proper container library will make garbage collection unneccesary.

One the other side I am avocating a more complete container librarys and one
argument against it is that one can allways use access types.

In Germany we say that the "cat bites is own tail" here.

Without garbage collection access types are pain in the bud. And when the
container library only stores "type element is private;" than one need to
use access types as element.

I have proven that both options are possible

I have implemented a garbage collected storrage pool for GNAT.

I also have created containers for "type Element (<>) is abstract tagged
private;" and I belive "type Element is array (Index range <>) of Item;" is
possible as well (Enabling collection of Strings). Both can't be done with
C++ templates - so we should not take the all mighty STL as an example.

Any thougts?

With Regards

Martin
