On the other hand, several implementation do not support it, but
support alternative interfaces.  This should have been discussed
in the SRFI.

Neither Kawa nor Guile support the new functions, but they instead
provide call-with-input-string and call-with-output-string.
Slib uses the latter.  MIT Scheme has neither interface, but it
provides a mix of both but using different names.

Personally, I think the srfi-6 procedures provide a convenient,
low-level, and efficient interface.  But there *is* alternative
prior art, which one could make a good case for choosing instead.
