Just because I haven't used DFV doesn't mean I don't know how it works. It's still perl, right?
When you have a code reference, the code being referenced does not get executed until someone dereferences it. It's really that simple. And consistant. Perl always works this way. Always. Well, unless you have a source filter, but I doubt DFV is a source filter (it's too complex).
This answer just convinces me that it's really an XY Problem - that you don't really want to dynamically create a code reference, instead, you probably want a tutorial on code references and closures instead.

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).
