Annotation type any not working properly

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Type Checking

Expected Behaviour

Variant 1:
Type 'any' allows any type except 'nil'. Type nil it's nil, not any.
@param cc any|nil should allow to use nil type

Variant 2:
When checking a type, you need to always have an argument, no matter what type. The argument must be specified in the method call. Сalling with an empty argument is not allowed

Variant 3: a special flag in param annotation that indicates an argument must be specified here

Actual Behaviour

---@param cc any
local function Test(cc)
	print(cc)
end

Test() -- no error

Type any allow nil type.

For example:
LUA + luabind C++.
C++ required argument on all bindings. Test(nil) and Test() have different behaviour for luabind.

Reproduction steps

1. Go to '...'
2. Click '...'
3. See error '...'

首先，在 Visual Studio Code 扩展中复现报告的注解示例：比较 @param cc any 和 @param cc any|nil 下的 Test() 与 Test(nil)。该 issue 提出了几种可能的语义，但没有指明源文件或测试；首先确定预期的规则，然后验证完成后的行为能够区分省略的参数和显式的 nil。
