Minor nit... Dijkstra was one of the authors of Algol 60 which had plenty
of control flow statements. He explicitly mentions goto with respect to
algol in his “considered harmful” note:
"Finally I should like to record (as I remember it quite distinctly) how
Heinz Zemanek at the pre-ALGOL meeting in early 1959 in Copenhagen quite
explicitly expressed his doubts whether the go to statement should be
treated on equal syntactic footing with the assignment statement. To a
modest extent I blame myself for not having then drawn the consequences
of his remark.”
However, he follows that with this:
"I remember having read the explicit recommendation to restrict the use of
the go to statement to alarm exits, but I have not been able to trace it;
presumably, it has been made by C. A. R. Hoare.”
which sounds like the “religion” being discussed. My feelings on that topic
are private, as I feel most religious beliefs should be :)
