# An operand of 'dataize' is brought down where it stands in the universe,
# under a name phino makes up for it, but the block the 𝔻 opens is headed by
# the operand as the entry spells it, the way the line binding its meta is
# commented, so a reader learns what the block brings down from its first
# line rather than from the line after it closes (#2145).
