name	version
IDEA version	[e.g. IC2018.2 EAP, CL2018.1.2]
EmmyLua version	[e.g. v1.2.5]
OS	[e.g. OSX 10.13.4, Windows 10]

What are the steps to reproduce this issue?（重现步骤？）

---@generic T
---@param _objects T[]
---@param _onCreate fun(obj:T)
function Builder:new(_objects, _onCreate)
    local myObject = {}

    ---@param _onPress fun(obj: tipOrTrick)
    function myObject:setOnPress(_onPress)

    end

   return myObject
end

What happens?（出现什么问题？）

The Builder:new() function knows the type of T, myObject:setOnPress() doesn't

What were you expecting to happen?（期望？）

Both to be aware of the type of T

Any other comments?（其它说明）

I started the implementation of this, the @param annotation already is aware of the 'T' by looking recursively to parent. But I can't figure out how to correctly infer it yet. Perhaps someone with more experience in the plugin can help me finish it? You can see the current implementation here: https://github.com/pouwelsjochem/IntelliJ-EmmyLua/tree/recursive_generic_type
