...ression that results in a class A instance or reference, we will get the complete version of the type. When we are making other types that include class A through inheritance or as a member variable, we may or may not need get the full definition for class A. For example if we have a "class A* m_a_ptr;" member variable, we don't need to know about A since we only need to know what type we need in order to layout the type which is a pointer here. If we inherit from class A or have a "class A m_a;" then the layout type needed here would be the full type. So we are very careful t...

How do you handle name lookup for nested classes? They have the same problem (they don't appear in all definitions) - don't appear in all descriptions of the outer/parent class. (in theory we could ensure there's always at least a declaration of the nested class - but we don't even do that if the nested class is unused) Is it just the case that Clang doesn't mind you adding a
