my ($first) = $string =~ /(["()])/;
<Editor's Note>
From perlop:
If the `/g' option is not used, `m//' in list context
returns a list consisting of the subexpressions matched by
the parentheses in the pattern,
i.e., (`$1', `$2', `$3'...).
Examples:
if ( ($F1, $F2, $Etc) = ($foo =~ /^(\S+)\s+(\S+)\s*(.*)/) )
So, by parenthesizing the character class containing the
characters you want to find, the regex will return that
character when matched.
The parentheses around the left-hand-side variable (here,
$first) are required, to put the expression in list context.
In scalar context, a regex will only return true or false.

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).
