Benny, Because I am showing a sample and just didn't think about it. :-) There will be a sample in the book source code.

Why not make it even more readable: condition creditcard_transaction: user.payment_method is credict_card condition low_discount_applied: applied_discounts < 10 when creditcard_transaction and good_payment_option and sale_on_weekend and weekend_club_member and low_discount_applied: apply_discount 5.precent I like your style but I would like to se a small application build on this.

Yes, including directly in the DSL some extensibility points, seems a great way to proceed. It is impossible to anticipate all needs in a DSL, but the ability to extend make it really powerful. alk.

I really like this. I have done something similar in the past when writing my own small DSL, which was nothing more than a somewhat complex string-processing language. It allowed the user to combine arbitrary functions and variables together in order to create new functions, then use the new functions later. It was a really, really, really clean way of being extensible.
