That is what *CORE::GLOBAL::open= coderef is for. And if it only makes things fatal when in a void context, then this shouldn't be much of a problem for module code that doesn't know whether the user might use this or not.
You can write code that would break in such cases but I don't consider such code to be reasonable so I don't mind. (:
open( FILE, "< this.txt" );
warn "Can't read this.txt: $!\n"
unless defined fileno FILE;

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.
