Once again, the most efficient solution would be to handle strings
as binaries internaly avoiding the use of extra layers such as a
bstring library or driver. Any time to have to communicate with
other applications via some Internet protocol, you have to convert
strings to binaries and that could be avoided.
Hence, I woud see:
- strings implemented as binaries within the interpreter
- a lstring library in order to manipulate strings as lists
