Thanks for writing rc! I’d forgotten about Duff’s paper and the exact circumstances of rc’s release until I read LukeShu’s and your replies.
I had a lot of fun with rc....
(Plan 9's `rc` was originally written for 10th edition Unix, and would later get ported back to Unix as part of Russ Cox's plan9port in 2003.)
