NAME
       PPI::Exception - The PPI exception base class

SYNOPSIS
         use PPI::Exception;

         my $e = PPI::Exception->new( 'something happened' );
         $e->throw;

         PPI::Exception->new( message => 'something happened' )->throw;
         PPI::Exception->throw( message => 'something happened' );

DESCRIPTION
       All exceptions thrown from within PPI will be instances or derivations
       of this class.

METHODS
   new $message | message => $message, ...
       Constructs and returns a new "PPI::Exception" object.

       A message for the exception can be passed, either as a string or as
       "message => $message". The message is available via the "message"
       method.

   throw
       If called on a "PPI::Exception" object, throws the object.  If called
       on the class name, uses the arguments to construct a "PPI::Exception"
       and then throw it.

       Each time the object is thrown, information from the Perl <caller(0)>
       call is saved and made available via the "callers" method.

       This method never returns.

   message
       Returns the exception message passed to the object's constructor, or a
       default message.

   callers
       Returns a listref, each element of which is a listref of caller(0)
       information.  The returned listref can be empty.
