Side discussion: why
while () { ... }
is interpreted as
while (1) { ... }
I can't find anything relevant in perldoc perlsyn.
$ perl -MO=Deparse -e 'while () {print "tick!\n"}'
while (1) {
print "tick!\n";
}
Update: Below is the deparse from perl 5.6.1. Above was 5.8.
$ perl561 -MO=Deparse -e 'while () {print "tick!\n"}'
for (;;) {
print "tick!\n";
}
Update 2: See more discussion in thread while ()

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).

are good places to start.
