There's special syntax for this: use Nothing (<code><span class='Nothing'>·</span></code>) for a placeholder non-name in the appropriate position, like <code><span class='Nothing'>·</span><span class='Ligature'>‿</span><span class='Value'>y</span><span class='Ligature'>‿</span><span class='Nothing'>·</span> <span class='Gets'>←</span> <span class='Value'>list</span></code>.</p> |
