R devel - Nov 2012 - built-in NAMED(obj) from within R

Hello,

Is it possible to retrieve the 'named' field within the header (sxpinfo)
of a object, without resorting to a debugger, external code, etc? In 
other words is there a built-in equivalent to the "getnamed"
subroutine
described here:

The goal is to ascertain whether a copy of an object has been made.

Thanks,
Ben

And much more than just NAMED :

    .Internal(inspect(x))

Then :

    ?tracemem

One demonstration of using both together is here :
