The global value false is the only instance of class FalseClass and represents a logically false value in boolean expressions. The class provides operators allowing false to participate correctly in logical expressions.
And—Returns false. obj is always evaluated as it is the argument to a method call—there is no short-circuit evaluation in this case.

Case Equality – For class Object, effectively the same as calling #==, but typically overridden by descendants to provide meaningful semantics in case statements.

Exclusive Or—If obj is nil or false, returns false; otherwise, returns true.
#define false_xor true_and
The string representation of false is “false”.
