Hi,

I use Perl once in a while, and still think that -> should not be replaced. Leave it be if that's possible.

    I find that many people do something like:

    $var->{key1}->{key2}->{key3}

    when the following should suffice:

    $var->{key1}{key2}{key3}

      I’m one of those people, and I’m not entirely sure why I do it. I’m fully aware that the later arrows are optional. The one arrow notation feels a bit asymmetric, and it doesn’t show that they all are refs in there, I guess.

      I usually write ${${$$var{key1}}{key2}}{key3}, or, very rarely $$var{key1}{$key2}{$key3} or an intermediate variant. I never use arrow dereferencing.

        Those are particularly unusual ways of doing it. But hey, TIMTOWTDI.
