What should other string-returning procedures do? John Cowan 20 Dec 2014 16:21 UTC

I think this is an excellent SRFI, and I support it.

However, it specifies only that `make-string` must return
a variable-length string.  What about `string`, `string-*case`,
`substring`, `string-copy`, and `string-map`?

My notion is that `string` ought to be free to return either a
variable-length or a fixed-length string, and that the others ought
to be guaranteed to return variable-length strings if (not iff) their
string argument is variable-length.

Also, what about conversions between fixed-length and variable-length
strings?  On Kawa, these would be no-ops, but on other systems they
might not be.

English-to-Russian-to-English mangling thereof: "Only on Barrayar you risk to
