--- Comment #7 from Boris Zbarsky <bzbarsky@mit.edu> ---
One note on terminology: I'm using "runtime" as "while rendering the webpage"
whereas "compile-time" is "while creating that thing the user will download and
use as a browser".  Just to make sure we're not talking about JIT-compile time
here, because in fact some of these checks _can_ be made at JIT-compile time,
and in SpiderMonkey's case we do just that for the "this" object in the common
case.
