law of code #4:

"thou shall not reveal code to the un-initiated"

More for your benefit than any need to keep code secret - they wouldn't understand it anyway...
The corollary is that you shall guide those seeking higher levels of understanding. The greatest service
to your fellow coder is leading them to better understanding of the arcane.

"None are so easy to deceive as those who don't wish to know (face) the truth..."
