That's not clear at all. How many of those <50% that do reference |this| 
want unbound |this| -- making sure that you take out those covered by 
method definition shorthands?

Two days ago, Kevin reiterated "[t]he precise way to say it would be 
that ~90% of function expressions in the code I analyzed were either 
object literal methods or did not depend on dynamic |this|."
