I have to disagree here. Arrays and Hashes may be about storage (I don't
think they are, though, since you can change the (storage) implemenation of
an Array or Hash via its metaclass and it can still remain an Array or

Not at all. The $ sigil implies a scalar, so what you get is roughly
my $y = (1, 2, 3).item * (1, 2, 3).item;
so $y ends up

Well, hyperoperators work fine on Hashes, they operate on the values,

the keys, %hash1 + %hash2 sums based on keys.) I would assume
that Bag should work in the exact same way. Dunno how Set should work
I'm honored that my letter generated so much activity, and thank you all for
your thoughtful responses. I'd like to address a few points.

This is going to be a rambling answer, as I have a number of questions
but no firm conclusions. Please bear with me.

Having Bags flatten in list context is pretty crucial to their being as

I just implemented Bag to the point where it passes the spectests.

However, in doing so, I discovered that I'm not really sure what Bags are
for, anymore.
