Yep. Shame on whomever wrote that code! :P

Yeah, I guess what I'm seeking is a concise way to write that. Maybe 
it's not deserving of its own construct, though. Can you think of a more 
general solution that gets half-way there? Maybe a pattern-matching 
thing akin to the way OCaml does case statements...

def x(*args)
  case args
    when [] then ...
    when [a] then ...
    when [a,b] then ...
    else ...
  end
end

That is totally un-Ruby, of course, so, I dunno.

'd be interested to hear.

Thanks,
