In [[SHARP APL]] and [[J]], Under is implemented as a [[close composition]], meaning that (using SHARP syntax) <source lang=apl inline>f¨g</source> has the overall [[function rank]] of <source lang=apl inline>g</source>. J uses <code>&.</code> for the close form and <code>&.:</code> for the rankless form. | |||
