Description:

Uninheritable provides a simple way to make a class uninheritable (unable to be subclassed from). While the technique to do this is not difficult, neither is it immediately obvious, and there is no standard exception for this.

require 'uninheritable'

class A
extend Uninheritable
end

class B < A; end # => raises a TypeError

Installation of "Uninheritable" requires Phil Thomson's installpkg. Thanks to David Black for his assistance with this on #ruby-talk.
