Wow, quick responses ;)

No, i don't know about PP.  I am just accustomed to having serious
output formatting control in fortran, c & derivitives, etc. for
printing ints, floats, hex, padding, ...  Its probably here, I just
don't know where it is.

I just extend the class for each individual program.  I wrote the
resize so I don't have to worry about what arrays I pass into the
function.  resize(n,def) just .clear's it and stuffs a bunch of 'def'
in to up to size n.  I haven't yet writting large ruby programs, so no
experience worrying about things.

Array *index* wrapping is useful in some cases (fibonacci numbers with
no extra assignments).  However, most of the time when I accidentially
go past the lower bounds I would like to know since a[x-1] wasn't
intended to set the value at a[9], but since x was zero it did.

nums = [1,2,3]   # nums[-1] = 3  mums[2] = 3, nums[-2] = 2, etc

	def calc_fib(n)
		a = [0,1,0]
		for i in 2..n
			k = i%3
			a[k] = a[k-1] + a[k-2]
		end
		return a[n%3]
	end
