While it's true that lockstep codepoint-in/codepoint-out processing is unfit
for many transformation jobs, it can handle simple transliterations like
ISO 9 (Cyrillic/Latin).  String-for-each is far more flexible: it can be
provide a string one codepoint at a time and accumulate results in a
string-port or similar device.
