Well, at least in Gecko+SpiderMonkey the open-ended-set stuff is a good 
bit slower than normal getters/setters; much harder for a JIT to 
optimize.  So no, it doesn't really work that nicely for things that the 
web does a lot right now like reading and writing inline style.

So my personal preference would be to use the IDL "getter" and "setter" 
syntax for vars only and use normal IDL attributes for actual properties.
