1995.0. "Are you the Pope?" by EVTSG8::ESANU (Au temps pour moi) Mon Sep 04 1995 07:03

(Mr. Gardner strikes again!)

From

Joseph E. Stoy, "The Scott-Strachey Approach to Programming Language
Theory", The MIT Press, 1985, ISBN 0-262-69076-4 :

Exercise 2 (p. 117). Let the integer  x  be a solution of  x = x + 1 .
Prove that you are the Pope. [...]

This is in  Chapter 7. Reflexive Domains , in which  P-omega , the
lambda-calculus  model, is presented.
