Here's another example(a modification of the example found  in pickaxe2, 
p 106):

if false
  data = "hello"
end

(1..3).each {data = "goodbye"}

puts data

--output:--
goodbye


That is equivalent to Java's call by value--but using references and C++ 
reference semantics, and the flat scope is converted to spheric scope 
with assignment semantics applying throughout any call by value passing.
