I am not aware of that puzzle, or what Jeff had in mind, but here is
my guess: it lets you add code to an 'any clause without breaking
the 'any, e.g. if you want to call a sequence of functions until
one of them returns non-none/false, but also need to do some
calculations in between, you could use something like:
any [
func1
to-none count: count + 1
func2
to-none count: count + 1
func3
...
]
