Yet another container

yac

Just remembered this gem from @crell at #tnphp: "Invent yet another container? You could call YAC, and shave it!" - igorwesome, _(*1)

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., _(*2)

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!, _(*3)
