I don't see why Perl needs interfaces in any form, they're just there to satisfy the compiler in statically typed languages, aren't they?
No they're not ;-) Not if we're using the term as used in Java land anyway. They're a way of talking about common behaviour that cuts across class hierarchy boundaries.
In Perl 6 they're subsumed by roles (a Java interface would the equivalent to a role without any implementation code.)
(Note: Apply my standard "I've not read A12 properly yet" disclaimer to the previous sentence, but I'm sure chromatic will correct me if I'm wrong :-)

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).

or How to display code and escape characters
are good places to start.
