I'm optimizing the generated V8/DOM bindings in Chrome. One thing I've
noticed is that any method that returns a JS 'boolean' ends with:
return result ? v8::True() : v8::False();
Both of those functions call into V8 proper, where they seem to invoke
a nontrivial amount of code. The same goes for v8::Null() and
v8::Undefined().
Since these values are, I would imagine, constants, is it possible for
me to call them once, store them in PersistentHandles, and then re-use
those cached values? That way I could reduce the above idiom to a
couple of inlined instructions.
