Hi,

I think it is not documented, and it's usually strange that people write code dependent on this order. However, to anwer your questions, you can look at MCPackageLoader>>#basicLoadDefinitions. More specific below:

What happens when I load a package?
Are all classes created first, and then methods are added, or classes are
loaded one-by-one with all their methods?

- new classes added

- new (versions of) methods are compiled

- old classes and methods removed

- retry definitions that were erroneous

- install all new methods

- notifications

- postloads

��

What about Slots? Are they added to classes after all classes are loaded?

No, they are added to the class when it is created

��

Do
they have their methods by that time?

It depends. If the class was not loaded before, it does not have methods. If the class existed and you're loading a different version, it'll have the old methods.

��

What is order of loading of classes? Alphabetical, or using some resolution
mechanism, or is it implementation detail?

It looks by looking at the code that they are sorted by dependency between them (for example, superclasses before subclasses).

But I did not look much further.

��

What happens when I unload the package? Is it inverse of loading so order is
reversed?

Apparently, (look at MCPackageLoader class>>#unloadPackage:) the order is reversed by dependency (first methods, then subclasses, then superclasses)
