because I can’t imagine why you would want to pop the last element off of an array if any element in it equals '2.
Don't try to analyze code logic. It's a proof-of-concept code. Perl does not care about it's logic
when execute it, so you should not too.
clarity
So, if don't wish to see proof-of-concept code without any sane logic, perhaps you want to see real code, here it is.
do_finish() removes element from @{$self->{jobs_a}}, after that we exit "for" loop in get_task().
Do you think it will be more clear if it will return number of element to remove, and we remove it outside for loop?

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).
