Rather than a new table adverb, I would prefer a conjunction that
asserted properties of a verb/noun: commutative, left-associative, and
right-associative come to mind for verbs, Hermitian and antiHermitian
for nouns, and there may be others. Then the existing adverbs like [x]
u/\ y and x u/ y could take advantage of the properties.

save about half the time.
NB. assuming the main diagonal could be interesting
