Or another approach: plain old prototype hacking.  True, you can't  
make "fixtures" (AS3's traits, i.e., type-constrained properties that  
cannot be removed or subverted).  Perhaps there ought to be a way to  
do that, since today's JS extends String by simply setting new  
properties of String.prototype (frowned upon among Ajax experts, but  
still done).
