Dynamic typing in Ruby also aids the use of false = false and 0 = 0.

In Java I can't suddenly say that my variable contains a 'False' value. I
would have to make my int = 0 and detect the rationale behind that specific
integer. Dynamic typing solves this because myVariable = 5 and later it can
equal 'false' when it really is false (rather than a
number that represents false)
