Isn't bool __invert__ behaviour "strange"?

(I can't remember reading "-" (minus) for a standard boolean
negation operator anywhere. Even C/C++ uses "!".)

Stop! What about the "not" operator? It's Python's operator for
negation.

Boole's original formulation uses some weird mathematical things to
emulate "not", "and" and "or". Focus lies on "mathematical" here.

And "a little" unreadable ;)
