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 True, elseFalse | (2) | 
Notes:
not a == b is interpreted as not (a ==
b), and a == not b is a syntax error.
