I don't think the multiple usage of $_ is problematic here.
According to perlsyn the global $_ gets localized in a foreach loop.
Indeed:
#!/usr/bin/perl
use v5.16;
use warnings;
foreach (1, 2) {
say for qw(a b);
say;
foreach (10, 20) {
say;
}
say;
}
__DATA__
a
b
1
10
20
1
a
b
2
10
20

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.
