Using "then" in ruby definitely isn't idiomatic and goes against convention.

Yeah I’m sympathetic to this argument and I myself am often annoyed by rubocop’s apparent heuristic of “is it possible to encode an opinion on this? Great then let’s do it” … but in this case, I think this rule is beyond justifiable.

Have used Ruby professionally for a few years now and had no idea "then" exists.
