+New: Checked, a lightweight and highly configurable checked integral
+
+$(REF Checked, std, experimental, checkedint) is a wrapper around any integral
+type that inserts checks against common sources of bugs: overflow in operators,
+mixed-sign comparisons, and casts that lose information.
+
+The example below illustrates the basic use of the facility:
+
+-------
+void main()
+{
+    import std.experimental.checkedint, std.stdio;
+    writeln((checked(5) + 7).get); // 12
+    writeln((checked(10) * 1000 * 1000 * 1000).get); // Overflow
+}
+-------
+
+By default, all checks are enabled and the program is aborted if any check
+fails. An implementation based on hooks discoverable by using Design by
+Introspection allows unbounded customizations of both the checks to do, and the
+enforcement policy.
