what's wrong :(

### NIM

import
  lua

proc NimMain() {.importc.}

proc get_hello*(state: PState): cint {.cdecl, exportc, dynlib.} =
  state.pushstring("Hello!")
  return 1

let
  test* = [
    Treg(name: "get_hello", `func`: get_hello),
    Treg(name: nil, `func`: nil)
  ]

proc luaopen_test*(state: PState): cint {.cdecl, exportc, dynlib.} =
  NimMain()
  echo state.isNil
  var lr = unsafeAddr(test[0])
  var nup = cint(test.len-1)
  state.openlib(cstring"test", lr, nup)
  return 1

### LUA
local path = "/your/global/path/test.so"
print("1")
local f = package.loadlib(path, "luaopen_test")
print("2")
local f = f()
print("3")
print(f.get_hello())

print("yay!")

### RUN
nim c --app:lib --noMain -o:test.so test.nim
lua main.lua
