I'm not much of a fan of operator overloading anyway. But I thought it was a nice thought experiment, and again, maybe acceptable for oneliners.
I still tried to cheat the system and go around the "useless use [...] in voix context" by using <<= instead of << because $magic << "Value"; returns $magic itself so $magic <<= "Value"; works fine.
Except it failed when trying to turn this: $magic << "Value" << "Other value"; into $magic <<= "Value" <<= "Other value";, because << is a left associative operator and <<= is a right associative one. Meanig you've just turned ($magic << "Value") << "Other"; into $magic <<= ("Value" <<= "Other");. Whoops.
So yes, the lesson is don't add new semantic to operators kid (yup, I'm looking at you C++).

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).
