 Proposal
 ========
 
-A new attribute on ``BaseException``, ``__suppress_context__``, will be
-introduced. The ``raise exc from None`` syntax will cause
-``exc.__suppress_context__`` to be set to ``True``. Exception printing code will
-check for the attribute to determine whether context and cause will be
-printed. ``__cause__`` will return to its original purpose and values.

 There is precedence for ``__suppress_context__`` with the
 ``print_line_and_file`` exception attribute.

 To summarize, ``raise exc from cause`` will be equivalent to::
 
     exc.__cause__ = cause
-    exc.__suppress_context__ = cause is None
+    exc.__suppress_context__ = True
     raise exc
