Use class_eval or instance_eval when triggering lazy load hooks:
- When lazy load hooks were triggered we were using `Object.instance_eval` which evaluates the block in the context of the class being passed. Most of the time that class was a `Class`. If one wants to define a instance method on the class then it wasn't possible. ```ruby class A; end; A.instance_eval do def foo puts 'bar' end end A.new.foo #> NoMethodError: undefined method `foo` A.foo #> bar ``` - This PR checks what object is passed when triggering the hooks and either call `class_eval` or `instance_eval`. My rational and assumptions being that if an instance of a class is passed, then the blocks needs to evaluate in the context of that instance (i.e. defining a method should only define it on that instance). On the other hand, if a Class or Module is passed when triggering hooks, then defining a method should define it on the class itself - #32776 Pushed me to introduce this change
