Thanks. That's going to be handy. One thing I am not sure of is if
Jeff and/or Heikki are planning to come back to this thread by the
feature freeze and do something about it for v19.

So let's see what happens, but I'll be happy to study this patch
opportunity in v20, be it in a complete form or a partial form (for
the latter we could assume that a portion of what you are suggesting
is committed into the tree in time for v19, leaving some hanging
fruits for v20).
