...yeah, and if I get paranoid I also check whether the stringify and/or (de)ref operators are overloaded, and maybe somebody changed shift and reverse via e.g. schwern's Function::Override... ;-)

I guess that if somebody changes $" globally, they have a reason, now don't they?

--shmem

update: inserted globally

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

    Humbug. If your function API isn't explicitely saying it's using the current value of $", then it shouldn't use its current value.

    Do not assume people haven't touched it. They have every right to, without having to appologize for it, to you.

      Keep cool. I didn't publish any function API, but I might do so.

      Anyways, you're right in "counting on the default value", and in production use $" should be localized. I just didn't find it being necessary in the context of this thread.

      --shmem

      _($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                                    /\_¯/(q    /
      ----------------------------  \__(m.====·.(_("always off the crowd"))."·
      ");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

    Don't forget code filters, too! :-) Just because it says "sub" doesn't mean it actually *means* sub! ;-)
