Also, a completely unrelated question for those who read this far. I
notice there seem to be two competing Ruby conventions for naming
methods. My copy of the Pickaxe book (first edition) uses
mixedCaseNaming. Other sources (Ruby itself, frex) use
underscore_naming. Is one of these prevalent, or is it whichever you
like better?
It's up to you, obviously, but underscore_naming is the popular method naming convention. In my little Ruby Chess program (*still* not done... haven't had time lately), I used underscore_naming for the "production" code, and CamelCase for the unit test code, but that was mostly by accident.
