 <h3 id="assignment"><a class="header" href="#assignment">Assignment</a></h3>
 <p>An <em>assignment</em> is one of the four rules containing <code><span class='Function'>ASGN</span></code>. It is evaluated by first evaluating the right-hand-side <code><span class='Value'>subExpr</span></code>, <code><span class='Function'>FuncExpr</span></code>, <code><span class='Modifier'>_m1Expr</span></code>, or <code><span class='Modifier2'>_m2Exp_</span></code> expression, and then storing the result in the left-hand-side identifier or identifiers. The result of the assignment expression is the result of its right-hand side. Except for subjects, only a lone identifier is allowed on the left-hand side and storage sets it equal to the result. For subjects, <em>destructuring assignment</em> is performed when an <code><span class='Value'>lhs</span></code> is <code><span class='Value'>lhsList</span></code> or <code><span class='Value'>lhsStr</span></code>. Destructuring assignment is performed recursively by assigning right-hand-side values to the left-hand-side targets, with single-identifier assignment as the base case. The target <code><span class='String'>&quot;·&quot;</span></code> is also possible in place of a <code><span class='Function'>NAME</span></code>, and performs no assignment.</p>
 <p>The right-hand-side value, here called <code><span class='Value'>v</span></code>, in destructuring assignment must be a list (rank 1 array) or namespace. If it's a list, then each <code><span class='Function'>LHS_ENTRY</span></code> node must be an <code><span class='Function'>LHS_ELT</span></code>. The left-hand side is treated as a list of <code><span class='Value'>lhs</span></code> targets, and matched to <code><span class='Value'>v</span></code> element-wise, with an error if the two lists differ in length. If <code><span class='Value'>v</span></code> is a namespace, then the left-hand side must be an <code><span class='Value'>lhsStr</span></code> where every <code><span class='Function'>LHS_ATOM</span></code> is an <code><span class='Function'>NAME</span></code>, or an <code><span class='Value'>lhsList</span></code> where every <code><span class='Function'>LHS_ENTRY</span></code> is an <code><span class='Function'>NAME</span></code> or <code><span class='Value'>lhs</span> <span class='String'>&quot;⇐&quot;</span> <span class='Function'>NAME</span></code>, so that it can be considered a list of <code><span class='Function'>NAME</span></code> nodes some of which are also associated with <code><span class='Value'>lhs</span></code> nodes. To perform the assignment, the value of each name is obtained from the namespace <code><span class='Value'>v</span></code>, giving an error if <code><span class='Value'>v</span></code> does not define that name. The value is assigned to the <code><span class='Value'>lhs</span></code> node if present (which may be a destructuring assignment or simple subject assignment), and otherwise assigned to the same <code><span class='Function'>NAME</span></code> node used to get it from <code><span class='Value'>v</span></code>.</p>
-<p><em>Modified assignment</em> is the subject assignment rule <code><span class='Value'>lhs</span> <span class='Function'>Derv</span> <span class='String'>&quot;↩&quot;</span> <span class='Value'>subExpr?</span></code>. In this case, <code><span class='Value'>lhs</span></code> is evaluated as if it were a <code><span class='Value'>subExpr</span></code> (the syntax is a subset of <code><span class='Value'>subExpr</span></code>), and passed as an argument to <code><span class='Function'>Derv</span></code>. The full application is <code><span class='Value'>lhs</span> <span class='Function'>Derv</span> <span class='Value'>subExpr</span></code>, if <code><span class='Value'>subExpr</span></code> is given, and <code><span class='Function'>Derv</span> <span class='Value'>lhs</span></code> otherwise. Its value is assigned to <code><span class='Value'>lhs</span></code>, and is also the result of the modified assignment expression.</p>

If it is preceded by <code><span class='Value'>atom</span> <span class='String'>&quot;.&quot;</span></code>, then the <code><span class='Value'>atom</span></code> node is evaluated first; its value must be a namespace, and the result is the value of the identifier's name in the namespace, or an error if the name is undefined. A parenthesized expression such as <code><span class='String'>&quot;(&quot;</span> <span class='Modifier'>_modExpr</span> <span class='String'>&quot;)&quot;</span></code> simply returns the result of the interior expression. A braced construct such as <code><span class='Function'>BraceFunc</span></code> is defined by the evaluation of the statements it contains after all parameters are accepted.
