### Bug or Regression

<code>f()</code>, <code>h()</code> (if <code>z</code>
evaluates to false), <code>i()</code>, <code>j()</code>,
<code>&lt;-c</code>, <code>g()</code>, and <code>k()</code>.
However, the order of those events compared to the evaluation
and indexing of <code>x</code> and the evaluation
of <code>y</code> and <code>z</code> is not specified,
except as required lexically. For instance, <code>g</code>
