Unable to use @enum or @alias type in table index (index signature) #2791
Description
I don't know if this is intended or not, but IIRC this is possible in typescript.
---@enum idx
local enum = { a = 'a', b = 'b' }
---@param tbl table<idx, string>
local function x(tbl) endWhen calling x with a table (e.g. x({ | })), I expect to receive completion for a and b, but I don't get that.

Surprisingly, it doesn't work with
@aliaseither -_-.I guess
@aliasdoesn't actually create an "alias".[-]Unable to use `@enum` type in table index (index signature)[/-][+]Unable to use `@enum` or `@alias` type in table index (index signature)[/+]tomlau10 commentedon Aug 12, 2024

This used to work perfectly fine, what broke it? I remember using this december last year with no issue at all. Is it the LSP or VS Code?

LSP. I don't use vscode.

Damn, I don't like this problem either.
I want to create a table with specific indexes defined via aliases, but I can't. LLS can detect if you're trying to access a key that isn't defined:
But it doesn't suggest existing keys when defining a table.
