Indeed - I wasn't assuming the code layout has anything to do with what we
are currently talking about.

Ah - if it's just a convenience, then it makes a lot more sense.
(I don't think we should be thinking of being able to change the macros
to rename definitions at a later date, but that was only a side point so
lets not worry about that for now).

In fact, what you're suggesting is the first step on the way towards the
FilterFactory concept.  I think noone really knows how to do
FilterFactories, but the idea was to use a combination of some provided
code and macro hackery to hide most of the messy details of making a new
element.  We need to get things working the messy way first, I think, but
that shouldn't stop us trying to work out how we're going to neaten things
up later.
