One of the things people were telling me when I was thinking about
local_scan() was that they wanted an efficient way of scanning messages,
without having to run an additional process. If you start using pipes,
you lose this efficiency.

Sure, you get better protection of Exim itself, but that wasn't the
point.

You can do that kind of thing already, using ${run or ${perl. The idea
of local_scan() was to be more efficient for those that couldn't afford
even the cost of ${run.
