there's no substite for using wantarray to check your calling context
Interesting example, though I fail to see how wantarray will help in this case:
sub use_wantarray { return wantarray ? () : 0 }
Wont work properly in your example either.... Note that the above sub is equivalent * to the recommended way to return false, i.e. simply return:
sub recommended_way { return; }
* except when used in void context, but that isn't relevant here.

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).
