G'day jamroll,
Welcome to the Monastery.
In scalar context, @array evaluates to the number of elements.
In list context, you'll get the actual elements.
Instead of concatenating with '.' (which forces scalar context),
you can just embed @array within interpolating quotes.
Here's an example showing all three of those scenarios:
$ perl -E 'my @x = ({}); say ">" . @x . "<"; say ">", @x, "<"; say ">@
+x<"'
>1<
>HASH(0x7fb6c68040b0)<
>HASH(0x7fb6c68040b0)<

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.
