This a a great idea! In this case the default string will be a random-access range, not a bidirectional range. Also, processing dstring is faster, then string, because no encoding needs to be done. Processing power is more expensive, then memory. utf-8 is valuable only to pass it as an ASCII string (which is not too common) and to store large chunks of it. Both these cases are much less common then all the rest of string processing.
dstring consumes 4x the memory, and this can easily cause perf degradations due to thrashing and poor cache locality.
