I know what a *boolean* is, just not why I would need
a built-in data type to express it.

Meanwhile, most university people don't get that
programming languages are tools that should be
employed to do useful things, not runes to be analyzed
like some Noam Chomsky/Indiana Jones would the
paleo-Etruscan from half-disintegrated tomb stones!

The worst part of all that is that if you do it enough
you start to like it. It is sneaky. Then you can never
move on. If kids think UML is relevant all hope is
gone. But I don't think they do - not those
