Nor i in this kind of system.  There is a kind of imperialism about
dynamic typing that spreads thru systems :-).

and then there is XML.

There is a lot of craft knowledge in these three communities
that it is helpful to leverage.  It is difficult to firewall
out all the design patterns in these three communities.

I'm not adding a garbage collector, nor an interpreter.

That was my intent, except I non-parsing uses I'd like to address
(request pattern matching for example).

To me it would seem the harder problems are
   (a) where it gets used,
   (b) how the perimeter is handled, and
   (c) what's it's relationship to XML?
Of those I only tried to address (b) in the proposal.

It would be good for other people to opine where they want
the chips to fall.
