README

Just remembered this gem from @crell at #tnphp: "Invent yet another container? You could call YAC, and shave it!" - igorwesome

Yet another container is yet another di container for PHP, inspired by Pimple and LazyMap. Basically blending the two together. When using it the LazyMap way it's very performant.

Defining parameters

$c = new Yac\Yac();
$c['env'] = 'dev';

Defining services

$c['session'] = function($c) { return new Session($c->env); };

Accessing parameters and services

$std = $c['std']; // pimple compatible
$std = $c->std;   // "fast" LazyMap way

Performance

Yac is much faster than Pimple!
