in thread Take reference and then dereference die() and warn()

I realize that; my error message is much longer than "failed", and I do not want to copy-and-paste it.

    OK, I understand your motivations, now.

    You still have numerous simpler ways to do it, such as storing your long error message in a variable (you actually had a $error variable in your original post) or doing something like this:

    $ perl -e 'use diagnostics; $die_on_err=shift; 0 or print "error messa +ge" and ($die_on_err? die $! : warn "\n" ) ' 0 error message
    or, yet simpler, using a subroutine such as the one proposed by Jenda in this post: Re: Take reference and then dereference die() and warn().
