forsworn mutable strings? ???

Mutable strings are ok for many tasks, but sometimes
immutable strings are better.

It's the same like wondering which style of programming is better for a task.
So, OCaml seems to be very open to different programming styles...
...why not to different kinds of strings?


At the time I have done it with String.copy and modyfing the copy.
But as soon as I has some time to look at the suggestions made here,
I may use them in a reimplementation of my module.
Thanks to *.mli this will not affect the user of the module. :)
