Sure :-)

Why not using the "in"-operator? I know that it doesn't really work for
undefined values in swf8. But nevertheless is much faster, for swf8 it
was about 30-40% less time, for dhtml 10-15% less time.
tested with:
//both runtimes need approx. 1sec to execute the code
var m=80000; //800000 for dhtml
var o={}; //var o={foo:true}
var d=new Date()
for(var i=0;i<m;++i)
//if(o.hasOwnProperty('foo')) ;
if('foo' in o) ;
Debug.write(new Date()-d);

The property isn't set to null if the previous return statement is
executed..

Hm, it should be easy to identify all setters since they're all named
"$lzc$set_xxx"!?
