Subj : Recalculating scope chain (i.e., 'with' statement).

It is said in books of lore that using the 'with'
statement is computationally expensive.  But why is
this so, if the scope chain is merely a chain of
object references?  Would not using the 'with'
statement merely amount to changing about two
references (that of the child scope, and that of the
parent scope)?

Separately, are there any plans to open up access to a
function closure via object references?

Thanks in advance!
