FWIW, attached is a little notification mechanism akin in spirit to NSNotificationCenter [1].

Usage example:

local Notification = require( 'Notification' )

-- register some observers
Notification[ 'WillDoIt' ] = function( ... ) print( 'one', ... ) end
Notification[ 'DidIt' ] = function( ... ) print( 'two', ... ) end
Notification[ 'DidIt' ] = function( ... ) print( 'three', ... ) end

-- dispatch some notifications
Notification( 'WillDoIt', 1, 2, 3 )
Notification( 'DidIt', 1, 2, 3 )

> one	WillDoIt	1	2	3
> two	DidIt	1	2	3
> three	DidIt	1	2	3
