You might also want to have a look at Lamport's paper "How to write a
long formula" (DEC SRC-119, 1994), possibly still findable at
<http://gatekeeper.dec.com/pub/DEC/SRC/research-reports/SRC-119.pdf>,
in which he relates some experience with notations for presenting
lengthy program-correctness formulas.
