I would like to see the third subtype of lua string : external string
. The content of the string is a C pointer rather than bytes array.
So that we can construct the long strings in O(1), it's useful when we
want to use lua string library to manage the memory in C side.
Or if we have many lua vm in one process, it can reduce the cost of
message passing.
