An Issue in coroutine mode with LuaRef

[Leon-zsl]

I use LuaBridge in my project for quite a long time. It works quite well until recently I am trying to support multi-coroutine mode in lua end.
As we know, different coroutine has different lua_State. When I'm going to push a LuaRef into the stack of the current coroutine (L), LuaRef choose to push itself into the stack of the coroutine it cached (m_L) when it is created, instead of the current coroutine (L). As a consequence, the current coroutine can not get the value it wants, so unpredictable things will happen...
My question is: is it possible to remove the cached m_L from LuaRef? or do you have any more elegant solutions to resolve or just bypass this issue?
For example:
when a lua coroutine want to get a property, which by coincidence is a LuaRef, like function getProperty in CFunctions.h, T is a LuaRef.
LuaRef will just discard the input L and use the cached m_L instead, like function push in LuaRef.h, L is discarded
After the push function returned, the LuaRef still does not exist in the current L, so the caller in Lua can not get the property it wants.

How do you actually use coroutines? Could you please post some code examples?
