See the current Perl documentation for exit.

Here is our local, out-dated (pre-5.6) version:

exit - terminate this program

exit EXPR

Evaluates EXPR and exits immediately with that value. (Actually, it calls any defined END routines first, but the END routines may not abort the exit. Likewise any object destructors that need to be called are called before exit.) Example:

    $ans = <STDIN>;
    exit 0 if $ans =~ /^[Xx]/;

See also die(). If EXPR is omitted, exits with 0 status. The only universally portable values for EXPR are 0 for success and 1 for error; all other values are subject to unpredictable interpretation depending on the environment in which the Perl program is running.

You shouldn't use exit() to abort a subroutine if there's any chance that someone might want to trap whatever error happened. Use die() instead, which can be trapped by an eval().

All END{} blocks are run at exit time. See the perlsub manpage for details.

[LanX]: what is the intention of your question?
[LanX]: why do you need to see the nodelet without votes left???
[marinersk]: LanX, the problem is that the lack of interface visual stability is disconcerting to me. The Nodelet appearing and disappearing is distracting, and despite over a decade, still troubles me. It jangles me.
[LanX]: I see
[marinersk]: I appear to be unusually dependent on spacial stability. I have had trouble from someone moving an object a mere four inches to the left.
[Eily]: I think the solution is to write posts so brilliant that you gain XP on each refresh, no matter how often :P
