I know you're memeing, but if I know my Lisp, just wrapping something in triple parens implies evaluating it three times. So you have an expression evaluating to a producer that produces another producer that finally produces a value?
I'm sure there's a legit use case for it. I just can't think of one.
That's (part of) why it should be a separate table to map the relation "Relationship". People can have more than one (polyamory, infidelity), and you could track fields like the start, end, status (e.g. flirting, dating, committed, engaged, married, ended) in there.
Not using it at all would be better, sure, but if you don't have that option for whatever reason, reusing it is the next best thing. Don't let perfect be the enemy of good.
