---@class with function return question

Nadie ha tomado este issue todavía.

so I have this (as a mockup):
```lua
do
---@class a
local a = {}

---@generic T
---@param self a
---@param new T
---@return T
a.extend = function(self, new)
--...
return new
end
end
```
and it's supposed to be inheritance for prototypes, right, but I'm trying to make the LS think that it returns the second parameter `new` and it does that and the LS thinks that, so far so good. So this
```lua
local b = a:extend{
n = 1
}
```
will make it like this:
but the problem is, that if I use `---@class b` here, then it will ignore what the function returns and I get this:
am I missing something or is it just not possible? Though, if I separate it into two statements like this,
```lua
---@class b
local b = {
n = 1
}

b = a:extend(b)
```
then I get what I want:
but it's not ideal, since it's two statements now and I can't use the `fun{}` syntactic sugar this way, which would be the whole reason, right. Is there a way to make it work? Also I'm unsure about how to properly word the title here

No se nombran archivos fuente ni pruebas. Reproduce los dos fragmentos de Lua de una línea y los dos de dos instrucciones; después, sigue la inferencia de tipos de LuaLS para declaraciones locales, anotaciones de clase, genéricos y valores de retorno de funciones. Se considera terminado cuando el comportamiento compatible está implementado y cubierto por una prueba de regresión, o cuando la limitación está documentada claramente.
