"wot he said" x 10 :-)

The video + audio to scart example struck me last night and providing  
expressive(?) examples of this to match so that one is less easily caught  
by tuples as arguments is a doddle.

cables = (audio, video)
connector = IScart.adapt(cables, "HDTV")

Assuming I haven't got totally the wrong end of the stick this shouldn't  
confuse anyone.

Now, do we have any similar simple but expressive analogy for utilities?  
Soap dispensers?

ISoapDispenser.utility().dispense() # agained, spelled out for clarity  
seeing as that's all the utility does.

I hope my analogies aren't too far off the mark. Helps me a lot not to  
think about what's really going on.
