Ruby Types introduces group of classes as eqivalent to some data
types in other languages such as
boolean and allows introspection
according to type of class too. In fact, partially replaces multiple
inheritance because introduces unlimited formal genericity for every
For example define:
class Boolean < Type def type_classes [TrueClass, FalseClass] end end
Then you can call:
foo = 5 bar = true foo.type_of? Boolean # returns false bar.type_of? Boolean # returns true
Binding back to classic behaviour works:
foo.type_of? Numeric # returns true
#type_types method of the
Type class you can achieve
also types inheritance by the same way as mentioned above.
