What is the use case for immutable strings? Why shouldn't strings be
mutable like they are in Scheme?
Generally if I know I don't plan to mutate something, I'd want to make
it immutable so the runtime system can notice if I make an error.
It's like an "assert" statement spread through the whole program.
