>>> range 1 :: [Integer]
[0]

>>> range 8 :: [Integer]
[0,1,2,3,4,5,6,7]

\(NonNegative n) -> length (range n :: [Integer]) == n

>>> rangeSize ('x','z')
3

>>> inRange ('a','z') 'e'
True

>>> inRange ('x','z') 'a'
False

>>> unsafeRangeSize ('x','z')
3

limit (lower,upper) x checks whether x is in the range from lower to upper. Don't expect a sensible result for lower>upper.
