One can use "$1[$2]$3[$4]$5" expecting no array (with impossible names according doc) interpretation.
No, the documentation does not say they are impossible at all:
Perl variable names may also be a sequence of digits, a single punctuation character, or the two-character sequence: ^ (caret or CIRCUMFLEX ACCENT) followed by any one of the characters [][A-Z^_?\] . These names are all reserved for special uses by Perl; for example, the all-digits names are used to hold data captured by backreferences after a regular expression match.
So @1, @2, @1066, etc. are all perfectly valid. They are just reserved for special uses by Perl.

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).
