Subject: Re: The Pebble in the Ruby Shoe

# Ruby aims to be a human friendly programming language that

an ones preference evolves, so does his knowledge of numbers: from counting, to integers, to rationals, reals, abstract, etc..

ruby is quite encompassing. array indices are integers: negative, zero, positive, and the ranges thereof...

irb(main):001:0> a=[1,2,3]
=> [1, 2, 3]
irb(main):002:0> a[0]
=> 1
irb(main):003:0> a[-1]
=> 3
irb(main):004:0> a[1]
=> 2

irb(main):006:0> a[0..2]
=> [1, 2, 3]
irb(main):007:0> a[0..-2]
=> [1, 2]

thus for me, with ruby, the shoe fits, and it fits well.
