Subject: What is the purpose of Vector.Query_Element?

Message-ID: <ca22434f-8216-4cbd-a4c0-46fea8e6cc98@googlegroups.com> (raw)
The package that defines Vector provides this procedure:
procedure Query_Element
(Container : in Vector;
Index : in Index_Type;
Process : not null access procedure (Element : in Element_Type));
Why is this procedure provided? Isn't `Query_Element (Vector, Index, Process'Access)` the same as `Process (Element (Vector, Index))`?
Thank you.
