Nothing major, only that it's closer to visual "forward" a la F#'s |>

I tend to see | as an indication of "OR" (bit or otherwise) rather than pipe
(which I completely understand why you picked it).

On a somewhat related note I had experimented with an overridden '|'
a while ago to lift conditions and compose them (which is what spurred
the get_digits question).
