Allow multiple versions of the same package to be installed and used simultaneously, avoiding the current inevitable conflicts. The problem is maybe not common with small projects, and it's encountered more in the enterprise projects that grow big and with many dependencies and makes library upgrades a difficult task. > > The WordPress use case does not need to declare a hierarchy of modules; it > needs to create a single boundary around an arbitrary set of code, which > might or might not happen to be a fully-populated vendor directory. > Agreed, so it seems that WordPress case is easily coverable with something like this, without a complex hierarchy of modules: ``` $wp = 'wordpress/core'; $pluginA = 'wordpress/plugin/plugin-a'; $pluginB = 'wordpress/plugin/plugin-b'; module_run($pluginA, function () use ($wp): void { module_add_dependency($wp); }); module_run($pluginB, function () use ($wp): void { module_add_dependency($wp); }); module_run($wp, function (): void { require ABSPATH . 'wp-includes/runtime-module-core-bootstrap.php'; }); module_run($pluginA, function (): void { require WP_PLUGIN_DIR . '/plugin-a/vendor/autoload.php'; // Includes Guzzle 6. require WP_PLUGIN_DIR . '/plugin-a/plugin.php'; }); module_run($pluginB, function (): void { require WP_PLUGIN_DIR . '/plugin-b/vendor/autoload.php'; // Includes Guzzle 7. require WP_PLUGIN_DIR . '/plugin-b/plugin.php'; }); ``` -- Alex
