What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

Types defined with an enum as their key should be accessible via both the runtime enum itself and the value they represent.

Actual Behaviour

A type defined with an enum as its key cannot be accessed with the enum's value.

Reproduction steps

---@enum building_id
local building_id = {
    ANY = -1,
    ONE = 0,
    TWO = 1,
}

---@type { [building_id]: { name: string } }
local building_attributes = {}

local anyName = building_attributes[building_id.ANY].name // Typed as "string"
local anyName = building_attributes[-1].name // Typed as "unknown"

Reproduce el problema de diagnósticos en el ejemplo de Lua proporcionado, comenzando por el manejo de las claves de enum en la ruta de comprobación de tipos del servidor de lenguaje. Compara el acceso mediante building_id.ANY con el acceso mediante -1 y utiliza como contexto la discusión enlazada en el issue; se considera completado cuando ambas formas resuelven el valor de la tabla como { name: string } en lugar de unknown.
