Subject: Re: Method constant arguments

Thank you all for the answers. I really liked the solution below. It can 
handle a lot of the things I want to do. I can set overwrite to true as 
default for instance.
I remember keyword arguments when I began learning Python and I liked 
it. Then I found Ruby and I couldnt go back ;) It would be a nice thing 
to have it in Ruby.

Thanks a lot.
