I'd say that the real 'trouble' is that strings are mutable at all.
Mutation-sharing substrings are only a minor additional semantical
annoyance.  They do enable new kinds of programs, and that makes them
valuable.

Also, there is the possibility on the horizon that we turn string-ref
etc into 'primitive generics' which means that people could implement
new kinds of strings using GOOPS.

Also, I still like the idea of using mutation-sharing substrings as
markers that allow O(1) access into variable-width encoded strings.
