+    <para>The ‘<literal>with</literal>’ language construct is now more
+    lazy.  It only evaluates its argument if a variable might actually
+    refer to an attribute in the argument.  For instance, this now
+    works:
+
+<programlisting>
+let
+  pkgs = with pkgs; { foo = "old"; bar = foo; } // overrides;
+  overrides = { foo = "new"; };
+in pkgs.bar
+</programlisting>

+    This evaluates to <literal>"new"</literal>, while previously it
+    gave an “infinite recursion” error.</para>

+    instance, you can write <literal>x + y</literal> instead of
+    <literal>builtins.add x y</literal>, or <literal>x &lt;
+    y</literal> instead of <literal>builtins.lessThan x y</literal>.
