Class typed table annotation

[Rouneq]

I've got a case where I'm creating a table with special key indexing rules (making it case insensitive). Since I'm developing under Luajit, I'm having to go through some hoops to iterate over the table. To complicate this further, I'm also sorting the keys to return them in alphabetical order. I decided to create a function on the table specifically to return this ordered iterator.

---@class ICaseTable : table
ICaseTable = {}

---@return ICaseTable @A table with case insensitive lookup.
local createtable = function ()
    local retval = {}

    -- Sorting logic
    local function __orderedNext(t, state)
    end

    retval.pairs = function ()
        return __orderedNext, retval, nil
    end

    -- Key indexing logic
    local mt = {
      }
    local t = setmetatable(retval, mt)

    return retval
end

--- Returns an iterator sorted by the keys
ICaseTable.pairs = function () end

return ICaseTable

That's all working fine. I'm wanting to better annotate the return so table is typed. When I use the following:

the table type annotation is treated as comment. Am I missing something or is this currently unsupported?

Use ---@alias ICaseTable table<string, any> or ---@class ICaseTable : { [string]: any } instead
