Well, ignoring... the next Ada will have vectors, sets, tables, lists,
and then some, such that more (queues, ...) can be built on top of them,
by default, and standardised.
AFAIKT the specifications are influenced by experience with 
libraries in at least Ada and STL. So if programmers have been
using arrays for things that arent't arrays, there must be
a problem other than availability of data structure libraries?
A general lack of awareness of how ADTs work?
Maybe, if the situation is really that bad, the standardised components
will ameliorate Ada programming WRT proper data structures.
