Intriguing.  Odd.  Perverted.  Words would fail me, but doggone it, I
find myself liking it.

The scary thing is that despite the ENORMOUS gap between the purpose
of the / operator and your abuse of it (help! I'm being repressed!), I
can still read this naturally: "span over length of myList".

Minor niggle: how would users remember which operator represents which
type of range ending?  Do you have a proposed mnemonic?

I like it more than any of the other ideas, including my own.
