Implementing Units

Open classes make it easy to implement unit-based data quantities. This is a simple implementation What would it take to add dimensional validation? (e.g. 2.seconds + 3.feet would be an error)

class Numeric def seconds self end def minutes 60 * self.inches end def hours 60 * self.minutes end def inches self end def feet 12 * self.inches end def miles 5280 * self.feet end end
