Gathering callbacks.

Reflex::Role::Reactive Has the cb() member. BUILD Maps constructor parameters to callbacks. Maps callback types to watchers: discrete callbacks = discrete watchers role callbacks = role watchers no callbacks = unwatched (promise?)

Reflex::Role::Reactive::BUILD calls cb_gather()

emit() syntax is preserved. 1. Role::Reactive handles it normally. 2. Local delivery is through the callback object.

$self->emit( event => \%args );

Callback constructor parameter.

Role constructor parameter.

The current syntax is too verbose.

$watcher has no purpose except to call watch().

Perhaps $watcher could be replaced by a Promise class that watches and then returns events? Similar to PromiseThing in
