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.
