Performance Improvements

[superdav42]

I'm intrigued by this project and toyed with creating something similar in the past. I'm wondering how strategy in the handler actually works. like in this example:
https://github.com/x-wp/di/blob/master/examples/simple-plugin/src/WC/Handlers/Product_Page_Handler.php#L24

#[Handler(
	tag: 'init',
	priority: 10,
	context: Handler::CTX_FRONTEND,
	strategy: Handler::INIT_JUST_IN_TIME,
	container: 'example',
)]
class Product_Page_Handler {

Would Handler::INIT_JUST_IN_TIME prevent the Product_Page_Handler class from being loaded until the 'woocommerce_single_product_summary' or 'woocommerce_before_add_to_cart' actions are called?

I want to avoid loading large classes with potentially long init steps unless they are actually used. is INIT_JUST_IN_TIME the only way to do this? What are the other strategies.

[seebeen]

INIT_JUST_IN_TIME - Will scan the handler for callbacks on defined tag - but will not instatiate the class.

If the can_initialize method returns true, and the context is valid - it will scan the handler for callbacks, and then register them.

Once the first hook fires, we check can_initialize() - we instatiate handler then, and run callback.
I designed it so handlers can be initialized much later than the first hook - so that they can use complex services.
