I suspect it's not used much -- I remember being surprised when I realized
we had it at the syntax level. I don't find '<?' and '>?' to be particularly
mnemonic.  Using <? as an lvalue is wierd in the
same way ?: is -- and I know that has been tricky to get right in a number
of cases.  I have no great love of it.
