Where after SICP and more on propagation of constraints

Mirko

I may have mentioned it already, but here it goes: SICP blew my mind.
Scheme blew my mind.

To my untrained CompSci mind, SICP is the equivalent of The Feynman
Lectures on Physics.

Two questions, one general, one specific.

1 - Chapter 3 was totally new to me. Recommendations for
further reading?

2 - Propagation of constraints. I use Screamer now. Any other CL
packages on that theme?

TIA,

Mirko

If you liked that, you might have fun with the book
"Lisp in Small Pieces" (a.k.a. "L.i.S.P.") by Christian
Queinnec:

Personally, I found the section on "Fast Interpretation" in
Chapter 6 to be most interesting, especially Section 6.1.9
"Variations on Environments", which is an excellent discussion
of various alternative implementations of lexical scope and
their performance & GC-behavior tradeoffs.

That cites prior art you might be able to find, such as Garnet's KR.

I thought that in cells constraint propagate in one direction only:
when the parent cell is modified, the daughter cells are updated.
I need propagation in both directions.
