The optimizer notices that $w and $z must be equal...

A C or C++ compiler might be able to make that optimisation, but Perl--No way!

What if $w is tied? What if my Bit2 $w; and my Bigint $z;?

Bogus question. Next?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco.
Rule 1 has a caveat! -- Who broke the cabal?
