You mean the "__context__" attribute of the exception? Java also allows
one to get the suppressed exception via "Throwable.getSuppressed"
method. But python3 suppresses the original exception, while java does
the opposite, so I'm ok to count it as a separate option (#4). Thanks.

Is it common for python3 code to be prepared to handle __context__? I
guess most developers just ignore it. So probably #1 is better?
