That's a bit dangerous isn't it?
#!/usr/bin/perl
use strict;
use warnings;
my @car = ('a', 'b,c');
my @cond = ('a', 'b', 'c');
if(join(',', @car) eq join(',', @cond)) {
print "FOUND\n";
}
else {
print "NOT FOUND\n";
}
This indicates that the arrays are the same even tho', clearly, they aren't.
If you're going to use code like this you have to know what are valid characters in your input arrays and be very careful in choosing your join string.

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).
