No they won't. Your array will still hold a copy and they all will be kept open.
I meant: "in a general situation". In this particular one I suggested to explicitly close the entries kept in the array. I also included a footnote mentioning the ref thing.
These file handles are references, are they not? You could try weaken these references in the array, and they'll automatically go away as normal — leaving just an undef in place.
This is a very interesting suggestion, although I have no experience myself weakening references. I won't try because this is not my problem, but I will keep it in mind for when it may be of some use for me...

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).
