I do wish he had mentioned the smart match operator ~~ as it nearly eliminates the confusion between EQ and ==. Of course, if you're dealing with legacy code, then you still need to understand both (or all three), but new coders might be well advised to start with smart match.
"Smart" match is a pile of shit, and anyone reading the manual description for it should conclude the same. You can't know what it does unless you can remember the details of a 23-item table.
It's undergoing major revision, and not a minute too soon.
