hey, i do that!

using LuaJIT's FFI, of course, which isn't exactly userdata... but
when i've used any buffer-like userdata object, it's trivially easy to
add a :substr([i,[j]]) method and a :setslice(s[,i[,j]]) too, if i
want it to be mutable.  the [,j] optional argument only goes there if
it's legal to shift content around, obviously.
