一些3.4.0新增功能的语法检查异常

Nobody has claimed this yet.

单独写lua没能复现
另外有没有强制修改类型的配置方式，比如
`---@class A
local a = {}
---@class B:A

---@type string|number
local c = 1

---comment
---@return A
---@return string|number
local function func1()
return a, c
end

---comment
---@return B
---@return number
local function func2()
local ta, tb = func1()
return ta, tb
end`
在这种情况下我怎么去配置使ta、ta符合返回值类型？

Start with the two screenshots and the provided Lua annotations involving A, B, and union return types. Reproduce the 3.4.0 syntax-checking behavior in the language server, then determine whether the reported diagnostics and the requested forced-type configuration can be addressed; done means the behavior is explained and a concrete configuration or limitation is documented.
