The C API reference is slowly progressing (do not expect anything too soon). I
have a question:
Is it correct to say for these functions returning C pointers:
lua_tostring()
lua_pushfstring()
lua_pushvfstring()
lua_newuserdata()
lua_touserdata()
lua_topointer()
lua_tothread() (?)
that "the returned pointer is valid while the element remains in the stack,
after that it could become invalid due to garbage collection."?
(Idle question: is there a reason why luaopen_base() returns 0 while
luaopen_table() and the other similar luaopen_...() return 1?)
