Subject: Re: Meaning of '!(...'    EG: "myObject.parse!(argv)"   ..?

Sorry Ryan... I'm still not getting it :-(

What is that exclamation mark doing? Could I substitute lets say a 'w' 
for the exclamation mark?

opts.send(:parse!, argv)   => opts.send(:parsew, argv)
opts.send(:parse, argv)    => opts.send(:parse, argv)

If I can, then I understand it. There are in fact two different methods 
'parsew' and 'parse'. But if thats true... then in my orginal code 
above, there wasn't a 'parse!' method defined.
