Sure we are agreeing here Bruno. Its just a matter of terminology. What you call
a published rule I call a rule. And what you call a rule I call a formula. I think
thats right ...

I was posting this not as a reply to your earlier article but just as a reply
to those people who kept saying that me repeating "rule not the same as formula"
doesn't make it so. I was giving them an example of exactly how rules and formulas
differ to shut them up (using my definitions of rule and formula throughout).
