The big story :
Each time a literal 1, 0 or undef is seen in perl source code, or
returned by a built-in, no new object is created by perl, but only
a reference to inner 'special' static constant.

Not at all. undef, 0 and 1 have no start or root, have they ?
You can still do
sub B::SPECIAL::AUTOLOAD { undef }
but I doubt this will be of any help.
