[jsbell, 2014/01/02 18:03:23]

Is there going to be any perf impact from this extra initialization in
attributes that don't throw (i.e. don't have EnforceRange, etc) ?

[sof, 2014/01/02 19:30:31]

The setter here being passed a simple number not bundled up in a valueOf() which
potentially throws? The overhead added:

 - stack allocation of an ExceptionState (with a trivial destructor.)
 - an UNLIKELY() check post-conversion, checking for exceptions.
 
I wouldn't think these combine to make much of a difference, but I don't have
hard data.

(FWIW, a semi-related data point: I worried about the same when adding
creationContext to ExceptionState objects, but haven't come across any
performance regressions against its addition.)
