I can replicate that. But more to the point, I also get the following result which is closer to the original post:
(using both Perl 5.6.0 on Win95 and Perl 5.005_02 on Solaris)
% perl -sle '"Hello" =~ /(\w+)/; print $1' -- -1=foo
foo
It's just plain wrong. Not only can $1 be assigned to, but afterward it refuses to take the pattern from the regex.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
