I have a very different experience with strings. I can't even remember a case 
where I wanted to modify an existing string (this includes all my C and C++ 
usage of strings). It's always assemble a string at one place, and then refer to 
that string ever after (and never modify it).

What immutable strings make possible is treating strings as if they were value 
types. Nearly every language I know of treats them as immutable except for C and 
C++.
