It is possible to validate the values, it's just traditionally a pain in the arse, because it involves using something like Variable::Magic or returning a tied scalar.

Yes. I've done it using a tied scalars, but the penalties -- not just performance, but the obfuscation factor -- makes it a complete non-starter IMO.

none of the implementations are as fast as a more traditionally written accessor.

If the performance penalty was a few percent, the syntactic sugar might be viable; but when it is closer 200% or 300% for subroutines/methods that already have a high overhead to work-done ratio, it simply isn't worth it.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
