[cells-devel] Thought For Someone Who Would Use Cells to Do Prolog

[Kenny Tilton]

If your Prolog-in-CL uses  slot readers/accessors, dependencies will 
arise. So the position (or whatever GUI layout attribute you have in 
mind) can be calculated by a cl-prolog operating over CLOS instances via 
CLOS slot accessor GFs, and the necessary dataflow will arise naturally.

The invocation of the cl-prolog computation will have to require dynamic 
insertion of initializing/configuring facts. The cell rule calculating 
the result will specify these facts from other cell values, and supply 
the calculating form. This then neatly embeds Prolog within Cells, with 
the Prolog both driving and driven by Cells. Yet one gets (I presume) 
the greater performance from a dedicated prolog working on a fixed set 
of facts (for the duration of a single calculation).

Not very sure of the above, btw.
