-     The @-operator doesn't work with foreach.
+     The @-operator works only on expressions. A simple rule of thumb
+     is: if you can take the value of something, you can prepend the @
+     operator to it. For instance, you can prepend it to variables,
+     function and <function>include</function> calls, constants, and
+     so forth. You cannot prepend it to function or class definitions,
+     or conditional structures such as <literal>if</literal> and
+     <literal>foreach</literal>, and so forth.
