FWIW, I still call myself an apprentice, as I still don't feel I've truly mastered Perl.

Minor point of posting style...

When specifying links to other nodes, use the PM-link tag: [id://11123691|first post]

Here, you used the anchor element (<a>): <a href=”https://www.perlmonks.org/?node_id=11123691>first post</a>

This causes problems for folks using one of the other domains the site is associated with (e.g. perlmonks.com, perlmonks.org, etc).

Not a huge deal, but one that really helps keep the cookies straight.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
