2.1.2 Boolean Operations

These are the Boolean operations, ordered by ascending priority:

Operation Result Notes x or y

if x is false, then y, else x

(1)
x and y

if x is false, then x, else y

(1)
not x

if x is false, then 1, else 0

(2)

Notes:

(1)
These only evaluate their second argument if needed for their outcome.
(2)
"not" has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b), and a == not b is a syntax error.
