Subj : Performance Interfacing to C++

I found an old message from  2001-07-04 via Google, which says:

>> ... interfaced JS with C ...
It seems to me, however, that these C functions (get, set, etc.) are called
by the engine subsequent to the engine's own internal JavaScript object
manipulation routines (i.e. the engine sets a property on the object using
it's own internal set method, then almost as an afterthought, it calls my
set method).
<<

Brendan Eich had confirmed that this is true.

I would like to ask if this is still true in 8 / 2004? And if so, why? I
can't see the reason, since the object has pointers declared for its getters
and setters to external C functions, which should solely be responsible for
getting and setting properties. Are there any plans to change this?

Brendan had also pointed to use JSObjectOps() to work-around that problem. I
looked at JSObjectOps(), but the docs are not very clear about it and rather
confusing. Can someone help on how to use this method?

Thorsten
