Why use rule?

[elucian]

We have chosen "rule" to define any kind of code in Bee. This is inspired from python, where you "def" something. But what? You def a class or you def a method or you def a function?

A Bee rule can be any sub-program: function, procedure, method, closure, class. So therefore a subprogram is a sequence of code called: business rule or simple: rule

That's the best I could come up with. Any other suggestion is welcome.
