            static VALUE
false_and(VALUE obj, VALUE obj2)
{
    return Qfalse;
}

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.

obj === other → true or false

            #define case_equal rb_equal

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

false ^ obj → true or false

nil ^ obj → true or false

            #define false_xor true_and

false | obj → true or false

nil | obj → true or false
