Thanks but I will be investing my time in human readable formats, even 
if we have to re-invent the wheel.  Sure maybe some concepts can be 
borrowed, but the format fails every test I just listed in my last 
email, including the ability to be handled with DSNLEXER.


Adopting this exact format, ain't where I will be spending any of my 
valuable time.

However, as I say, I will read through it looking for concepts.

But what we will end up using will look like the lispy stuff.
