Here's some fun; reverse the string and the regex in the
statement, eg.:
if ( "" =~ /^\Q$answer/i ) { default() }
elsif( "YES" =~ /^\Q$answer/i ) { affirmative() }
elsif( "NO" =~ /^\Q$answer/i ) { negative() }
Now the user can type "y", "ye" or "yes".
Or if you want you can build a case statement:
SWITCH: {
$answer =~ /^yes|y$/ && do { affirmative(); last SWITCH; };
$answer =~ /^no|n$/ && do { negative(); last SWITCH; };
default();
}

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).
