I'm sensing more consensus than we had last time round on this issue, as
well as more problems with the status quo. Historically I think that's
the last vestige of smart-pointer-like behaviour in any. I think
majority and safety should prevail on this one, so the UDC is now
deprecated (and will not be in the final release) in favour of an
explicit empty query.

Historically this also turns back the clock a little, as empty was what
was originally supported, but also raises another question over
something I removed a while ago: should a clear function be added to
support the more explicit approach? Ie a.clear() as opposed to a =
any().
