Please, *never*, *never*, *never* send a "courtesy copy" of a public
answer as a private mail when answering on a mailing list unless you
have been _explicitly_ asked to provide such a copy.

Otherwise, you set up _two_ different communication channels that the
person you are showing your "courtesy" then has to answer separately.
It is a great nuisance and additional work and hassle.

That _is_ the right syntax.  $foobar is a duration in #{ ... #}, and you
pass it by writing it down, as 2 or 2.. or 2.*3/2 or any other way of
writing a duration.

The first version where this would have been possible, judging from the
commit logs, would have been 2.15.6.  But there is little point in not
getting the current 2.15.x release instead.
