As perl needs to know the arguments for use lib before calling lib's import method, every expression used there is implicitly in a BEGIN block equivalent. So I often use a construct like this in my code:
#!/usr/bin/perl
use strict;
use warnings;
use FindBin ();
use lib do { (my $dir=$FindBin::Bin)=~s|/foo/|/bar/|; $dir };
This can also be used with taint mode to untaint the value of $FindBin::Bin:
#!/usr/bin/perl -T
use strict;
use warnings;
use FindBin ();
use lib do { $FindBin::Bin=~m|^(/.*)| or die "Can't find myself"; "$1/
+../lib" };

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).
