What is the argument to the last of these h()'s?
I get that h() is a cryptographic hash function, that ➡ is a callable
function and actual parameters for it (which can be evaluated to produce
some sort of output), and that ■ is an actual parameter. All that makes
perfect sense. The part I don't understand is what the juxtaposition
"➡■" means. Does it mean to hash the 2-tuple (➡,■)?
