Just one more question. What about $x{@y}?
You tell us? Try It To See? Tutorials: Basic debugging checklist?
I don't know what this means, do you have any idea?
$ perl -MData::Dump -e " @x = 1..2; $y{@x} = @x; dd \%y "
{ 2 => 2 }
$ perl -MData::Dump -e " @x = 1..4; $y{@x} = @x; dd \%y "
{ 4 => 4 }

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).
