What is the difference between @{\@foo} and @{@foo}?
Um... they're both the wrong way to write @foo, but the second one's more inefficient, but caring excessively about efficiency of bad code that you should refactor anyway is a premature optimization, so ... umm... it's a trick question, with the answer of "There's no difference; you'ld never use either one in production code?"
Do I win? :-) Or did I miss something subtle? :-(

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).
