Lesson learnt:
When you ask someone to look at the documentation, don't be surprised when the
look at the documentation :)
Yes you are quiet correct, those traits were added after Beta. There is not
currently a set of generated docs which detail them, besides inline docs in the
repository.
Hopefully Beta 2 will be released soon, probably later tonight. Although I have
some bad news for you, lua_acquire_ptr is no longer permitted, along with
cpp_acquire_ptr, as a trait for a function. I was never happy with them having
dual roles and version 2 seems a good a time to sort that out.
Traits are now split into three categories Parameter Traits, Function Return
Traits and Stack Traits. lua_acquire_ptr and cpp_acquire_ptr are now Stack
Traits i.e they work with OOLUA::push and OOLUA::pull respectively.
I know the namespace is called OOLUA, that is the convention I use for
namespaces, but honestly the name of the library is OOLua as in Object Oriented
Lua[1].
