Although I normally neither use nor need prototypes in Perl, I'd
still love to see them being extended in such a way that you could make
regular Perl functions behave like Perl builtins in every respect
(think of overriding print, system, etc.). I've come
across some discussion along these lines on p5p (e.g. here),
but I think things never went beyond just being discussed.
(This is not my entire Perl 5 wishlist, btw, but the other items
are still too vague / not thought-out enough yet, that I would dare to
present them to this audience :)

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.
