Could you or Oliver provide a little more detail? For example, if
exception support is enabled, will C++ exceptions be converted to
Python exceptions? Is this automatically global support, or does it
need to be enabled per module, class, method, ? with a sip keyword?
Thanks in advance.

There is only one place I'm aware of in PyKDE (KProcess) where the
absence of operator support has been a real problem (no
corresponding method call). I've added a method (not an operator)
to support this in PyKDE in the upcoming release. I'll add operator
support for this case (<<) as well, and then review the rest of the
overloaded operators down the road (operators are in sip 3.6).

PyKDE will have a bug fix release maybe early next week. I haven't
finished writing all of the unit tests, but I've caught enough bugs
to make a release worthwhile (plus patches/additions from Gordon
Tyler and Hans-Peter Jansen). 

I'll get a sip 3.6 compatible release out after that and then get
back and finish the test writing/debugging.
