Dynamic dispatch

Intent

dispatch the control based on the environment, but delay enumerating the cases

Motivation

we don't know at the time of writing the code what are the different cases to dispatch on

Implementation

(nearly) invisible in php

Examples

$case($arg);
$object->$method($arg);
call_user_func($calleable, $arg1, $arg2);


Note

A more elaborate form of dynamic dispatch is Method Chaining
