Um, yes; missed that out.

Ahh, I wasn't clear enough.

Within M2Crypto/SSL/Connection.py, I have "class Connection:..." Then, 
within M2Crypto/SSL/__init__.py, I have "from Connection import
Connection". This is so that clients can say "s = M2Crypto.SSL.Connection()"
instead of "s = M2Crypto.SSL.Connection.Connection()".

Because of this, I can't just do "from M2Crypto.SSL import SSLError"
within Connection.py. __init__.py's "from Connection import Connection"
creates a circular reference.

What's a nice way to fix this fine mess? ;-)

Thanks. Cheers.
