Simon Simpson programmer

Question

In Raymond Smullyan's book Satan, Cantor, and Infinity, the Sorcerer refers to a method of achieving self-reference which is "remarkably similar to Simon Simpson's method of programming" (near the end of the chapter entitled Self-reference and Cross-reference). I have tried looking him up but cannot find anything about a programmer called Simon Simpson - does anyone know anything about him?

Answer 1

From page $135$ of Smullyan (right before the Solutions at the end of Chapter 12):

"Tomorrow," said the Sorcerer, "before we leave this island, I would like us to visit the station of Simon Simpson, who is the youngest and most progressive roboteer on this island. I've heard he is a bit on the vain side, but also that his program system is a very simple and elegant one, and definitely worth learning."
