grep (/$filename/i, $key) foreach my $key (keys %path_versions)
FYI, this form of statement modifier is syntactically incorrect (in addition to doing nothing with the output of grep if the statement was modified so it could compile). See Statement Modifiers in perlsyn.
Specifically, a for loop statement modifier cannot use a named loop variable, but instead uses the implicitly localized (or 'topicalized') default scalar $_. E.g.:
>perl -wMstrict -le
"my @words = qw(foo bar baz);
print qq{'$_'} foreach @words;
"
'foo'
'bar'
'baz'

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).
