I think scain is right. However, it is too late to do a site-wide policy IMO, because it would be retroactive (i.e. would cover previously posted code without the authors' permission). So the best we can hope for is that monks optionally define the license with code posts or add something like this to their homenode:

Unless otherwise noted, all code authored by "$code or die" on perlmonks.org is free software which you can redistribute and/or modify under the same terms as Perl itself.

Which /me is about to add to my homenode. You should be able to negate this license on individual code posts.

Updates: removed superfluous "it" from license statement - btw what's the correct spelling of license?
Added link to perl license.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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.
