I agree, thanks for the link. Unfortunately, I find the complete lack of syntax to make it even harder to read than Lisp macros (which I don't personally find difficult, but some do). Additionally, having to use numbers to indicate operator precedence seems a bit strange. Of course, Lisp solves this by always using parentheses, but I would be curious to see if there is a more elegant way of handling this than the numeric approach (or even the approach suggested in their proposed changes to Logix).
