Hi,
May you please share your experience or preferences for rules engines
written in or used from Racket?
My goal is to:
1. Allow rule definitions separate from the code (though I view rule
definitions as programming to be performed by the programmer).
2. Allow rules to be defined in modules.
3.
e clues or pointers where I might start?
Best wishes,
Grant Rettke

Ashley play around with it in the REPL first just to see how it works eg:

with Clojure.
My goal would be to get DrRacket into a state where it was basically a

Hi,
Just listened to Rich Hickey's talk "Simple Made Easy":
http://www.infoq.com/presentations/Simple-Made-Easy
He mentioned implicitly a coding style where anything that is not
callable uses a square bracket. The let family is one example. I think
another one that fits are class constructors for
