To me it seems like the Python shell inconvenience of "did you mean quit" when you type exit (or the other way around, I can't recall). Clearly they mean `true` regardless. Beyond True, False, and Nil I don't see what else this could apply to–the slope isn't that slippery. If it is an easy win and it makes transitioning easier, why not.
