Your comment on Item related to loop, is clever and interesting.

About point #1, how do you relate it to #3? Do you feel as I do it's a  =

matter of point of view? An item for the client adding something to a  =

container, and is an element for the container, thus the Element_Type  =

instead of Item_Type? I was interested in the question in a more general=
  =

way than containers (the same question rise in other patterns too), this=
  =

is just that the case of containers speaks easily and the Ada standard  =

containers use this naming convention.
