# or: my $ref = "str$_"; # this is a purely symbolic reference,
+access is the same as above
I don't see how that is a symbolic reference? I think this is (had to think a while to come up with something contrived, here):
my $class = 'CGI';
my $version;
{
no strict 'refs';
$version = ${"${class}::VERSION"};
use strict;
}
print $version # e.g. 3.05 on my machine
In other words, we construct a variable's name ($CGI::VERSION) out of expanded variables ($class), and expand (it's almost like a string eval()) the result in turn to return the value stored under the constructed variable's name.
...mmmm still not really put elegantly, sorry.

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).

are good places to start.
