It seems specific to the context, and should be defined there.

Feature #12515: Create "Boolean" superclass of TrueClass / FalseClass
https://bugs.ruby-lang.org/issues/12515#change-61160

----------------------------------------
Since Ruby 2.4 is unifying Bignum/Fixnum into Integer (https://bugs.ruby-lang.org/issues/12005), it seems reasonable to do something similar for TrueClass / FalseClass, and create a proper Boolean hierarchy. The implementation would be fairly straightforward and should be back compat unless someone already has a "Boolean" class at toplevel out there.

Given the compatibility implications of Integer, this Boolean proposal is even less intrusive.

Sample implementation:

~~~
class Boolean < BasicObject; end
class TrueClass < Boolean; end
class FalseClass < Boolean; end
~~~
