Comment (by hvr):

 Replying to [comment:40 simonpj]:
 > The implementation has a special case for methods whose name starts with
 an underscore.  The user guide doesn't mention this.  Could it please do
 so?

 Btw, I noticed the documentation added contains the following paragraph:

 {{{#!xml
 <para>If no MINIMAL pragma is used, then all methods
 without a default will be requried, excluding methods with a
 name that starts with an underscore.</para>
 }}}
