I think this is too strong of a statement.  We use ropes extensively
at Google (we call them "cords") and frequently see very real gains.
I agree though that they're not a good choice for the generic string
type in a language like Lua.

It seems that ropes could be implemented as a userdata in Lua.  The
userdata's uservalue could reference the underlying string objects.
