Function Chaining - FnChain
“Provide a mechanism for appending functions to others, retaining access to all chained functions. Evaluating a Function Chain variable, should invoke each appended function in order. Extra functionality could include the removal of functions and the ability to clone and extend exiting chains.”
Property Event Listening - PEL
“Allow callbacks for property change events on an object.”
Multi-Functions - MultiFn
“Allow multiple implementations of a function based on different arguments. e.g. if you want different code to run if a function is called with an Array as opposed to an Object.”
