If you look at the listing I gave Oliver of the M/F Collection
hierarchy, you will see references to classes on Arrays. No idea if
people use them much. (Yes, they are used indirectly to support 'true'
Collection classes). But the important factor is your, "What I like
about it is it's directly supported by the language".

Perhaps it can be achieved using M/F methods - but if you look at the
proposed Class Structure for Collections drafted by J4 (Standards) - you
are SOL. Just don't hold your breath that this structure will be
expanded any time soon.
