Re: strings rationale

[Tom Lord]

       The inconvenience [of read-only-string?] is in the need to use

       for this before modifying them.

Please explain more carefully what you mean by this cryptic comment.

Where do you find the use of `read-only-string?' inconvenient?

What have shared substrings got to do with whether or not
`read-only-string?' must be used?


        a simpler, uniform string representation seems better

What does "simpler, uniform string representation" mean in this
context, specifically.
