The first variation is obviously better suited for chaining.

Additional functions:

|

|
=over 4
|
||
|
|
||
|
=item C<flash $type, $message>
|
||
|
|
||
|
Display a C<$message> in the flash of type C<$type>. Multiple calls of
|
||
|
C<flash> on the same C<$self> will be merged by type.
|
||
|
|
||
|
On the client side the flash of this type will be cleared before the
|
||
|
message is shown.
|
||
|
|
||
|
=item C<error $message>
|
||
|
|
||
|
Causes L<to_json> (and therefore L<render>) to output a JSON object
|
||
|
that only contains an C<error> field set to this C<$message>. The
|
||
|
client will then show the message in the 'error' flash.
|
||
|
|
||
|
The messages of multiple calls of C<error> on the same C<$self> will
|
||
|
be merged.
