Description
This works in Intelij but not with your extension
---@class Test
local Test = {
someval=404
}
---@return Test
function Test:__call() end
setmetatable(Test, Test)
local t = Test()
-- No completion for the following
t.
As i note it seems that setmetatable might not even be accounted for and that only the fact __call is in the same table makes it work in InteliJ, though i am not sure.

Research direction
Start by reproducing the Lua snippet and checking completion after local t = Test() and t.. Trace how the extension infers __call return types and whether setmetatable is considered; done when the returned Test type exposes someval completion.
