Okay, I gotta throw my hat in the ring here...
sub insert_after_first {
my ($ndx, $arr, $elt, $ins) = (0, @_);
$ndx > @$arr and return while $arr->[$ndx++] ne $elt;
splice @$arr, $ndx, 0, $ins;
}
Update: Here's a version that is a little more
efficient, removing one boolean comparison from the loop.
sub insert_after_first {
my ($ndx, $arr, $elt, $ins) = (0, @_);
$arr->[$ndx++] eq $elt and last for 0 .. @$arr;
splice @$arr, $ndx, 0, $ins if $ndx <= @$arr;
}

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).
