+``noexcept`` Policy
+====================
+
+Extended applications of ``noexcept``
+------------------------------------------
+
+As of version 13 libc++ may mark functions that do not throw (i.e.,
+"Throws: Nothing") as ``noexcept``. This has two primary consequences:
+first, functions might not report precondition violations by throwing.
+Second, user-provided functions, such as custom predicates or custom
+traits, which throw might not be propagated up to the caller (unless
+specified otherwise by the Standard).
