Between [E(X) || X (<-) F]
and [E(X) || X <- unfold(S, F')]
there is very little difference,
*provided* the compiler knows about unfold and treats it specially.

I've been thinking that we wouldn't really need
syntax for iterating over the elements of a tuple
if the compiler knew how to handle
[E(X) || X <- tuple_to_list(T)].
It's a little more long-winded than
[E(X) || X <-: T]
but a lot more obvious.
