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.

    [Cosmic37]: greetings earthlings please can someone improve my pathetic perl knowledge
    [Cosmic37]: I have 2 files each with datetime and other data in unknown order and I want to find rows from both files matching by datetime and output them combined/ concatenated
    [Corion]: Sure
    [Corion]: Do you have any specific interests or general Perl knowledge?
    [Cosmic37]: should I slurp? should I grep? Noble Lords I wish you good karma and beg your advice
    [Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
    [Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
