Added anon symbols and gensym support to maru 2.1.
Use gensym in some form expanders that used _var_ bindings.

Thanks for sharing code, yes. But please put it in some online code
repository. This would make it easier for us all, i think. What's your
opinion on this, Ian?

This may not be news to list subscribers, but wouldn't the Raspberry Pi 
make a great target for Frank etc. ? ->

The Model A / B naming brings up memories of my own childhood computing 
introduction on the BBC Model B (along with Logo and turtles, speech 
synthesizers, the first dot matrix printers, sound synthesis.. we had 
quite a progressive school and the underrated Acorn products were quite 
versatile for their time - when these were replaced with first 
generation IBM PC clones when I was around 12, it was something of a 
step backwards).

No worse or better than any other system; the point is precisely that
it's a pretty standard Linux system (if rather low-powered). Why do
you think specifically it's a good target? If Frank builds on GNU, it
should be straightforward to build it for R-Pi…

(I think Raspberry Pi, other than its unfortunate reliance on non-free
software, is an excellent thing; I know Eben Upton, who is behind it,
and was fortunate enough to see his first tiny computer prototype some
years ago. I'm very excited about its aim of getting more children
interested in programming. I'm just not sure what the connection is
here, other than the obvious one of new, simpler models of programming
and children.)

That's entirely intentional, right down to the model A being the one
very few people will probably buy!

I think the limited capabilities would be a great visceral demonstration 
of the efficiencies learned during the FONC research.

I was thinking in terms of replacing the GNU software, using it as a 
cheap hardware target... some FONC-based system should blow the GNU 
stack out of the water when resources are restricted.

Now that's an exciting idea.

People complain about *only* having 256MB (128MB in the A model) but
that is way more than is needed for SqueakNOS and, I imagine, Frank.
Certainly the boot time for SqueakNOS would be a second or less on this
hardware, which should impress a few people when compared to the various
Linux on the same board.

Fortunately, some information needed to port an OS to the Raspberry Pi
was released yesterday:

The GPU stuff is still secret but I don't think the current version of
Frank would make use of it anyway.
