=begin
Trying to redefine the infix division operator for the Float initially appears to have no effect.

class Float
  def /(other)
    "magic!"
  end
 end
 puts 10.0/2.0
 # -> 5.0

But when another infix operator is added the infix division operator suddenly takes on the new definition!

class Float
  def /(other)
    "magic!"
  end
  def *(other)
    "spooky"
  end
end
puts 10.0/2.0
# -> "magic!"

These results were returned when these programs were run in isolation.
