=head1 NAME

Mail::Message::Body::Delayed - body of a Mail::Message but not read yet.

=head1 INHERITANCE

 Mail::Message::Body::Delayed realizes a Mail::Message::Body

 Mail::Message::Body::Delayed
   is a Mail::Reporter

=head1 SYNOPSIS

 See Mail::Message::Body

=head1 DESCRIPTION

Message bodies of this type will be replaced by another type the moment you
access the content.  In this documentation you will find the description of
how a message body gets delay loaded.

=head1 OVERLOADED

=over 4

=item overload: B<"">()

(stringification) Returns the body as string --which will trigger
completion-- unless called to produce a string for C<Carp>.  The latter
to avoid deep recursions.

example: stringification of delayed body

 print $msg->body;   # implicit by print

 my $body = $msg->body;
 my $x    = "$body"; # explicit by interpolation

=item overload: B<@{}>()

When a body object is used as being an array reference, the lines of
the body are returned.  This is the same as using the C<lines> method.

=item overload: B<bool>()

Always returns a true value, which is needed to have overloaded
objects to be used as in C<if($body)>.  Otherwise, C<if(defined $body)>
would be needed to avoid a runtime error.

=head1 DIAGNOSTICS

=over 4

=item Error: Package $package does not implement $method.

Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not.  Probably you should investigate this and probably inform the author
of the package.
