# An operand is brought down by a whole run of 𝔻, so a λ function it fires on
# the way sits one level deeper than the firing waiting for it, and the metas
# of the two are told apart by which firing of the entry each belongs to. The
# judgment each firing is commented with says the same thing from the other
# side: the outer one was fired while 𝕄 reduced the program and the inner one
# by the 𝔻 bringing the operand down, under the binding it was bound to (#1306).
