Thanks, great idea for the defglobal.
When it comes to the rule name ( similar_rule ), what happens if this user
function was called multiple times simultaneously? Couldn't there be
problems with the rule over-writing itself? And wouldn't there be siilar
problems for the ?s1 variable?
Cheers,
Matt

You could use the "gensym" function to give you a unique symbol to use
for a variable name, and then use "build" to create your defglobal the
same way you've done here for the defrule; or use gensym to create a
symbol, but use it as a key to store your ArrayList with "store" and
"fetch".
