I say
one
three
five
two
four
Why?
- Weell $one is sure to go first.
- $three is sure to go right after $four is created.
- "five" is sure to be printed before $four (or $two) gets cleaned up.
I'm not sure the order in which $four and $two will be destroyed (because perl doesn't guarantee order of destruction), but I vaguely recall something about closures going away last, so that's why i'm going with that answer.
update2: er, actually, forget what i said about closures.
two goes before four because the closure is invoked (duh).
So I guessed right, but by the time I got to writing down why, things got fuzzy :)(i rushed)

update: I just checked on my
perl v5.6.1 built for MSWin32-x86-multi-thread (ActivePerl Build 638), and I guessed correctly :)
MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!" | I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README). | ** The third rule of perl club is a statement of fact: pod is sexy. |

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
