in thread Perl bug ?

what gets really passed is $errors
Why? I would expect the result of the && operation to be passed.

    yes, and the result of something_false && something is something_false. the second part is never processed.
      Oh, I see! Thanks for enlightening me.

        Maybe the confusing thing is, that not the value of $errors is the result (undef), but $errors itself, so it will be used as an alias to the subroutine. (maybe that wasn't expressed correctly but I hope it's clear what I mean)
      Now I get it, thanks. Agree. That's probably most amazing way to shut yourself 3 times in one line of Perl.
