To copy a single argument for every function call, it should have no axes, so we enclose it into a unit. This example would work just as well with Table (`⌜`), although maybe the interpretation is a little different. The reason it matters that Each accepts unit arrays is that arithmetic primitives (as well as the Depth modifier `⚇`) use Each to match their arguments up. Want to add a point (two numbers) to each point in an array? Just enclose it first. -- cgit v1.2.3
