Ack! Sorry, too early in the morning, hadn't had enough coffee.
That does *not* work, because you always refer to the bottommost
subclass's nifty ("this.nifty" is always the bottommost function), so
you end up endlessly recursing. Wow that's an easy trap to fall into.
No, it's either use the function's name unadorned, or use
arguments.callee and pay the performance penalty. Personally, I
prefer using the function's name. :-)
