MiniScript defines the following operators (listed in order from lowest to highest precedence):

Operator	Meaning
A `=` B	assignment
A `or` B	logical OR: true if either operand is true
A `and` B	logical AND: true if both operands are true
`not` A	logical negation: true if its operand is false, and vice versa
A `isa` B	type checking
A `==` B	equality comparison: true if operands are equal
A `!=` B	inequality comparison: true if operands are not equal
A `>` B	greater-than comparison
A `<` B	less-than comparison
A `>=` B	greater-than or equal-to comparison
A `<=` B	less-than or equal-to comparison
A `+` B	addition or concatenation
A `-` B	subtraction or string trimming
A `*` B	multiplication or replication
A `/` B	division or reduction
`-`A	unary minus (numeric negation)
`new` A	instantiation
`@`A	address-of (reference function without invoking it)
A `^` B	power: A raised to the power of B
A`.`B	dot operator

Operators >, <, >= and <= support chaining:

x = 42
if 13 < x <= 100 then  // same as if (13 < x) and (x <= 100) ...
	print "foo"
end if
