To copy a single argument for every function call, it should have no axes, so we enclose it into a unit.</p> <p>This example would work just as well with Table (<code><span class='Modifier'>⌜</span></code>), 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 <code><span class='Modifier2'>⚇</span></code>) use Each to match their arguments up. Want to add a point (two numbers) to each point in an array? Just enclose it first.</p> <a class="replLink" title="Open in the REPL" target="_blank" href="https://mlochbaum.github.io/BQN/try.html#code=KDwxMOKAv8KvMTApICsg4p+oMuKAvzMsMeKAvzfin6niiY3in6g04oC/MSw14oC/NOKfqQ==">↗️</a><pre> <span class='Paren'>(</span><span class='Function'><</span><span class='Number'>10</span><span class='Ligature'>‿</span><span class='Number'>¯10</span><span class='Paren'>)</span> <span class='Function'>+</span> <span class='Bracket'>⟨</span><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>3</span><span class='Separator'>,</span><span class='Number'>1</span><span class='Ligature'>‿</span><span class='Number'>7</span><span class='Bracket'>⟩</span><span class='Function'>≍</span><span class='Bracket'>⟨</span><span class='Number'>4</span><span class='Ligature'>‿</span><span class='Number'>1</span><span class='Separator'>,</span><span class='Number'>5</span><span class='Ligature'>‿</span><span class='Number'>4</span><span class='Bracket'>⟩</span> ┌─ |
