Examples

class Foo
  include AbstractType

  # Declare abstract instance method
  abstract_method :bar

  # Declare abstract singleton method
  abstract_singleton_method :baz
end

Foo.new  # raises NotImplementedError: Foo is an abstract type
Foo.baz  # raises NotImplementedError: Foo.baz is not implemented

# Subclassing to allow instantiation
class Baz < Foo; end

object = Baz.new
object.bar  # raises NotImplementedError: Baz#bar is not implemented
