I am talking about the semantics of Perl and you seem to be talking about the operation of perl.
Where do you think the semantics of Perl come from? The holy writ of magic candy-flavored flying unicorns? (However more maintainable that might be, there are actual and deterministic algorithms behind those semantics, which is sort of exactly precisely what people expect from a programming language.)
Feel free to argue with you think the semantics of Perl should be. Unless they match the documented and tested and empirically verifiable behavior of multiple versions of Perl, they're wrong, and you're wasting your time.
However much someone used to Python might think that parentheses make a list of constant expressions into a list in Perl, they don't. They merely group the expressions to disambiguate intended precedence. Perl's semantics aren't a matter of anyone's fiat, unless you want to anthropomorphize the code.
