bindbc-lua :: Return tables from D

[luaaaa via Digitalmars-d-learn]

Hi. I got a problem when I used bindbc-lua. I wanna return Lua 
table by D function like this:

**Simple example (Working)**
```
import std.stdio:writeln;
import std.conv:to;
import bindbc.lua;
void main() { // dmd 2.097.2 x64 on Mac & LUA_51, static
        lua_State *L = luaL_newstate();
    luaL_openlibs(L);
        string str = `print("Sup! I'm Lua!")`;
        luaL_loadbuffer(L, cast(const(char)*)str, str.length, "line");
        int error = lua_pcall(L, 0, 0, 0);
        if(error !=0)
                writeln(lua_tostring(L, -1).to!string); // Working fine
}
```

**Return Lua's table by D function (Can't compile it)**
```
import std.stdio:writeln;
import std.conv:to;
import bindbc.lua;

void main() { /* dmd 2.097.2 x64 on Mac & LUA_51, static */
        lua_State *L = luaL_newstate();
    luaL_openlibs(L);
        luaL_register(L, cast(const(char)*)"funcD", test);
        string str = `x = funcD()`;
        luaL_loadbuffer(L, cast(const(char)*)str, str.length, "line");
        int error = lua_pcall(L, 0, 0, 0);
        if(error !=0)
                writeln(lua_tostring(L, -1).to!string);
}

static int test(lua_State* L) {
        lua_newtable(L); // Make new table => [0:test_data]
    lua_pushstring(L, cast(const(char)*)"0");
    lua_pushstring(L, cast(const(char)*)"test_data");
    lua_settable(L, -3);
    return 1;
}
```

Please any advise me. Thanks!
