page-wide program examples

I’d like to have some program examples extend the full
width of the page in PDF output. I thought I could put the
<programlisting> elements within an <example> or
<informalexample> element, and set the pgwide attribute to 1 (which you
can do with tables and figures). However, <example> and
<informalexample> don’t support the pgwide attribute.

 

As a temporary workaround, I’m inclined to put the
<programlisting> inside a <table> or <figure> and set the
pgwide attribute.

 

Has anyone else found another simpler way to create page-wide
program examples?
