... loop execution will continue regardless of the state of the array unless an explicit loop exit is made ...
Hmm, really? I always thought the while-loop EXPR was re-evaluated after each iteration:
my @a = (3, 4);
while (do { say "yo"; @a })
{
say "hi mom";
shift @a; # no explicit loop break out
}
say "bye mom";
__END__
yo
hi mom
yo
hi mom
yo
bye mom

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).
