That's why there were three options. :) Pick one and toss either some speed 
or some memory.

Personally, the combination per-object .ISA property and per-class @ISA (or 
just give the class its own property hash) seems the most perlish. It's got 
the least size cost, but it's both the most expensive in terms of 
worst-case time and complexity.

Whatever get's mandated is fine by me. I don't do any of that newfangled OO 
stuff anyway. :)
