Represents the between operator.

The left operand must be a single value, and the right operand must be a 2-element list which defines a range from a lower bound to an upper bound.

This operator returns true if the left operand is greater than or equal to the lower bound and less than or equal to the upper bound. Consequently, 1 between {1, 5} evaluates to true, while 1 between {5, 1} evaluates to false.
