I did not want to lecture ;)
Hmm I am a little bit confused now because I have provided #terminate
with a defaulted parameter for exactly the reason above.
Anyway I think Tom's idea to use an instance variable @args (defaulting to ARGV)
with an attribute accessor reflects the spirit of the original design
much better.
I will try to find half an hour to do that for fun this weekend and I
will send it, feel free to use it or to loose it ;).

Cheers
