In what decate was it good practice introducing a dependency on an external module in order to get the exact same two substitutions hidden in a sub:
#---------------------------------------------------------------------
+---------
# trim
#
=head1 trim(string)
Returns the string with all leading and trailing whitespace removed.
Trim on undef returns undef.
=cut
sub trim{
my ($val) = @_;
if (defined $val) {
$val =~ s|^\s+||s;
$val =~ s|\s+$||s;
};
return $val;
}
#
# trim
#---------------------------------------------------------------------
+---------
If it really bothers you just add one line to your code and be done with it.

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).

or How to display code and escape characters
are good places to start.
