[Feature Request] @mixin - @class specific syntax to define applied mixins

What

A way to indicate that the members of a @class type are applied to a subject @class outside of the inheritance chain

Technical

@mixin type, ...
Adds the values of type, ... to the subject class' definition. Mixins are applied in the order they are specified; values of the same key are overwrote as each mixin is processed

Example

This:

---@class Mixin1
---@field foo number
---@field bar number

---@class Mixin2
---@field bar string
---@field baz string

---@class Subject
---@field key boolean
---@field foo boolean
---@mixin Mixin1, Mixin2

Would get interpreted as

---@class Subject
---@field key boolean (defined by field; wasn't altered by mixins)
---@field foo number (defined by field, overwrote by mixin1, not overwrite by mixin2)
---@field bar string (defined by mixin1, overwrite by mixin2)
---@field baz string (defined by mixin2)

Use case

I currently have sub-classes that get assigned valves from reusable dictionary tables outside their inheritance chain. The only way to document those modifications is to statically define the fields each time a mixin is applied

Aucun fichier ni test n’est indiqué. Commencez par suivre la façon dont le language server analyse les annotations @class existantes et l’héritage, puis déterminez où s’intégreraient l’application ordonnée de @mixin et l’écrasement des champs. Le travail est considéré comme terminé lorsque la syntaxe est analysée avec les règles de précédence indiquées et couverte par des tests pour plusieurs mixins et des collisions.
