You should think of "$a =& $b;" as "make the symbol table entry $a
reference the same PHP value bucket as $b. If the $a symbol table entry
was in use before it just changes it to point at the same PHP value
bucket as $b. It is a symbol table re-assign.
As stated before I´m aware of the problem, OTOH I see how a php-dev expects it to be... couldn´t you invent a kind of biometric identification or quantum signature? ;)
