 [http://core.trac.wordpress.org/browser/tags/3.3.1/wp-
 includes/functions.php#L1182 The do_enclose() function] looks through post
 content for enclosure-worthy URLs, requests the URLs it finds, and stores
 in post meta.

 I use sample code and dummy URLs in my posts: e.g.
 !http://example.com/song.mp3. Right now `do_enclose()` finds the mention
 of the MP3, adds it to post meta, which later outputs in `rss_enclosure()`
 or `atom_enclosure()`. If I want to remove the enclosure from final markup
 I can attach to the `added_postmeta` action to remove a value after it was
 requested and inserted or act on the markup generated by `rss_enclosure()`
 or `atom_enclosure()` by emptying the string.

 I would like to filter out the auto-discovered enclosure link before it is
 processed by !WordPress, looked up in the database, and HEAD requested. If
 a filter existed on the parsed enclosure links I could remove links from
 dummy domains such as "example.com."
