 Implementation Discussion
 =========================
 
+Note: after acceptance of this PEP, a cleaner implementation mechanism
+was proposed and accepted in PEP 415. Refer to that PEP for more
+details on the implementation actually used in Python 3.3.
+
 Currently, ``None`` is the default for both ``__context__`` and ``__cause__``.
 In order to support ``raise ... from None`` (which would set ``__cause__`` to
 ``None``) we need a different default value for ``__cause__``.  Several ideas

 Abstract
 ========
 
-PEP 409 allows PEP 3134 exception contexts and causes to be suppressed when the
-exception is printed. This is done using the ``raise exc from None``
-syntax. This PEP proposes to implement context and cause suppression
-differently.
+PEP 409 introduced support for the ``raise exc from None`` construct to
+allow the display of the exception context to be explicitly suppressed.
+This PEP retains the language level changes already implemented in PEP 409,
+but replaces the underlying implementation mechanism with a simpler approach
+based on a new ``__suppress_context__`` attribute on all ``BaseException``
+instances.
