# one step of a scan that is looking for one hit. Every scan in this file
# wants it, so it is stated once here.
#
# `Bool.or` is an ordinary function and reduces both of its sides, so a scan
# written with it reads the whole list even when the head answers. The rest of
# the scan arrives as a thunk, which is a value, and only the arm that wants
# it applies it; handed in as an ordinary argument it would be reduced before
# this def could decline it.
