Well, we don't really use pull requests, but other than that I don't see
why not to at least consider such improvement.

I'm not a heavy user or range types, so I can't really judge how useful
that is in practice, but it seems like a fairly natural extension of the
existing operators. I mean, if I understand it correctly, the proposed
behavior is equal to treating the element as a "collapsed range".
