I am just curious which methods people use for this very common problem and which is the most popular
Generally I'll just use a grep and double negation e.g
my @array = qw/ a list of words /;
print "yep, it's there"
if !!grep { $_ eq "of" } @array;
__output__
yep, it's there
Nice and efficient in newer versions of perl (5.6.1+ ?) as it won't build a list IRC. Even quicker would be a simple regex
my @array = qw/ a list of words /;
print "yep, it's there"
if "of" =~ /\b (?: ${\join('|', @array) }) \b/x;
__output__
yep, it's there
It's not quicker on it's own (list size etc will effect performance) but if you prebuild the word list it should be quicker than grepping every time.

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).
