Hello All,

Is is possible to add a parent class for TrueClass and FalseClass?
I always found it strange that there was not a concept to group true and false together.

e.g.:

class TrueClass < Boolean ; end class FalseClass < Boolean ; end # replaces the hack: module Boolean ; end TrueClass.include(Boolean); FalseClass.include(Boolean); 

In our code, we often want to validate that a value is of a certain type.

case(value) when String ... when Integer ... when true, false ... # Boolean # alt: when TrueClass, FalseClass  end # or def valid_args? value.kind_of?(String) end def valid_args? value.kind_of?(Integer) end def valid_args? [true, false].include?(value) [TrueClass, FalseClass].detect { |klass| value.kind_of?(klass) } end 

Does it make sense to others to have a way to group true and false together?

Thank you for your thoughts,
Keenan
