 <p>The four roles (subject, function, two kinds of modifier) describe expressions, not values. When an expression is evaluated, the value's <a href="types.html">type</a> doesn't have to correspond to its role, and can even change from one evaluation to another. An expression's role is determined entirely by its source code, so it's fixed.</p>
-<p>In the table, <code><span class='Value'>?</span></code> marks an optional left argument. If there isn't a value in that position, or it's <a href="#nothing">Nothing</a> (<code><span class='Nothing'>·</span></code>), the middle function will be called with only one argument.</p>
