In the same category, to see if $bar is in @foo:
my %foo = map { $_ => 1 } @foo;
if ($foo{$bar}) {
...
}
or faster and using less memory:
my %foo;
undef @foo{@foo};
if (exists $foo{$bar}) {
...
}
Of course, for a single test, grep is easier and often faster:
if (grep $_ eq $bar, @foo) {
...
}

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).
