There’s a comment in ‘A Retrospective’ (1978, I think - it’s in the 1978 BSTJ edition

`UNIX Time-Sharing System’; I have a tenth-anniversary reprint called ‘UNIX System

Readings And Applications’) by Dennis Ritchie about how a syntax for non-linear

pipelines has already been proposed. /dev/fd wouldn’t have existed yet, so does

anybody know what he’s referring to here?

Whoever it was, I bet it was Doug.
