* The [Eager] annotation is used to mark classes that should be initialized eagerly at startup.
5+
*
6+
* This annotation is typically used with object declarations in Kotlin,
7+
* which are lazily initialized by default.
8+
* By annotating an object with `@Eager`, you indicate that the object
9+
* should be initialized as soon as the program starts, rather than waiting until the object is first accessed.
10+
*
11+
* This annotation is also used to mark abstract classes whose subclasses should all be initialized eagerly.
12+
* When an abstract class is annotated with `@Eager`, all its subclasses are also initialized eagerly.
13+
*
14+
* Note: This annotation requires the use of reflection to find and initialize the annotated classes.
15+
* Therefore, it should be used judiciously to avoid potential performance issues.
