I see "R" being used multiple times in the expression

seems like it wasn't array-combinator codegolfed enough

I know that you are joking, but in fact I have further golfed it down to reduce the repetition : )

it's the only pattern I saw in array language videos - you guys keep golfing until everything is used only once, even though combinators become impossible to untangle
