Would globals work for you?

[alexg@powerbook]/Users/alexg/Desktop(28): cat load_me.rb
$global=10
local=20
[alexg@powerbook]/Users/alexg/Desktop(29): cat main.rb
load 'load_me.rb'

puts $global
puts local
[alexg@powerbook]/Users/alexg/Desktop(30): ruby main.rb
10
main.rb:4: undefined local variable or method `local' for main:Object  
(NameError)
