But now we discover our counterparts in the US thought **this** was the good guy??

This week's @cassidoo.co challenge: deal a deck of cards.
For something different, using the #Io language. As a pure prototype-based language, the object model is a neat fit, but it took some wrangling with the standard library to find the right tools for the job.
