Amen........ we still use Blaze on certain projects, but its GUI tools are
considerably more tedious to learn than the syntax of JESS. Its like trying to
write a document using dropdown list boxes and buttons to select the words. The
natural language may be a step forward over lisp style syntax - or it may not. You
still have to know THEIR reserved words and THEIR syntax and punctuation. The main
advantage we've seen of the natural language is that it is easier for the customer
to understand and validate the rules, but not to write them.
