Subject: Ruby equivalent for Lua first-class functions?

I think one of Lua's nice features is that all functions are first-
class functions. That makes it possible to override behavior like
this:

-- Sample stolen from Wikipedia
local oldprint = print           -- Store current print function as
oldprint
print = function(s)              -- Redefine print function
  if s == "foo" then
    oldprint("bar")
  else
    oldprint(s)
  end
end

How would you write the above sample using Ruby?


Grtz,
