+---
+Since @laravelphp 8.79 it is possible to resolve variadic dependencies out of the IoC container.
+
+This is quite useful for type-hinting and static analysis and allows us to bind a set of concrete implementations to an abstraction layer.

+🔥 Eloquent scopes pair very well with complex relation queries
+
+Scopes should also have @method annotations. They make the model more self-documenting & better supported in IDEs

+⚡️ Database Tip
+
+Every database performance guide is repeating the false statement stating WHERE LIKE '%search%' queries can't use an index. That is just not true! Most probably your database can't, but PostgreSQL implements trigram indexes which will make this really fast!
