Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

    You were somehow expecting an answer to your "Why?" that didn't involve opinion?

      You were somehow expecting an answer to your "Why?" that didn't involve opinion?

      No. I was expecting a justifiction to back up the opinion expressed. You gave none.

      Start with: <lvalue(s)> = @{ <some reference expression> };

      I contend that:

      • One thing you want to know is: "Where are the value(s) being assigned coming from?":

        And the above expression it is easy to see that: "it's getting the values by dereferencing and array ref".

      • Only then do you think about: "Where is it getting the array ref from?"

        Which you get by examining the (simple or complex) expression contained.

      This new syntax: <lvalue(s)> = <some reference expression>->@*; forces you to skip to the end to work out what is going on.

      That's an opinion backed by reason.
