Abstract

Cyclic ports are like infinite string and bytevector input ports: they produce the elements of a given sequence repeatedly, forever. While their intended use is as reusable seeds for SRFI 271 random ports, they are also useful whenever a repeating sequence of one or more bytes or characters is needed.
