# The memo of '--acyclic=plausible': 𝔼 is a function of the formation it
# fires, so two bindings spelling one term fire one formation twice, and a
# run firing it afresh each time mints two symbols for one value and fires
# everything under the second once more (#1476). The 'evaluate' lines of
# 'L_pair' fire 'a' and then 'b', which spell the very same sum. Under the
# mode the second firing takes what the first answered: it reduces nothing,
# mints nothing and lands 'b' on the very symbol 'a' came to. The protocol
# still writes the firing of 'b' at its own site, with the answer the firing
# of 'a' made, named after the line that made it, and with no operand line
# under it, since none was reduced (#1874).
