{{Built-in|Bind|∘}} is a [[primitive operator]]. It shares the glyph [[Jot]] (<source lang=apl inline>∘</source>) with [[Beside]]; in many dialects the two operators share the name [[Compose]]. Its [[derived function]]s can only be called monadically. | {{Built-in|Bind|∘}} is a [[primitive operator]].
