How can I annotate a class factory?

[ZegWe]

I have a class factory like this:

function CreateClass(szClassName, szBaseName) end

And would use it like this:

---@class ClassA : ClassBase
local tbClassA = CreateClass("ClassA");

---@class ClassB : ClassA
local tbClassB = CreateClass("ClassB", "ClassA");

How can I annotate the class factory so that I have no need to annotate the generated classes? Since there were too many class defines writed by other colleagues and it's impossible to modify all their code.
