Subject: Regarding rand

I was reading Learn to Program by Chris Pine yesterday, in one bit it says:
	' Note that I used rand(101) to get back numbers from 0  to 100, and
that rand(1) always gives back 0.'

I was wondering if rand() could support syntax like:
   rand(0..100)

Here's my go:

def random(value)
	if value.class.method_defined? 'entries'
		entries = value.entries
		entries[rand(entries.length)]
	else
		rand(value)
	end
end

this works with arrays and hashes too.

I'm coming to Ruby via RoR and i'm loving it, I should be writing a
web app and i'm playing with Ruby instead.
