I'm trying to fix up the exceptions for the _sqlite3 module I'm

My initial version just used C# Exception classes, but StandardError
is not a normal class, so that was insufficient. I looked into how the
existing modules did it (using PythonContext.EnsureModuleException)
and started to implement that but I've run up against a bit of a
roadblock: PythonExceptions.CreateThrowable is internal. It's not a
problem for anything in IronPython.Modules, of course, because of the
accursed InternalsVisibleToAttribute, but that doesn't help me much
:).
Is there a public way to create and throw a Python exception (i.e. a
BaseException instance)? For now I'm just using reflection, but I
would like a better way.
There's a public PythonOps.CreateThrowable. It just forwards the call
to the internal PythonExceptions.CreateThrowable.
Speaking about exceptions. Is there a way to convert the
System.Exception to the Python exception when I know the
System.Exception is a Python exception?
I ran into this when I played with data binding and
BindingValidationError event. This event is raised when a setter throws
an exception. So I threw MyException. But in the event, the
event.Error.Exception is System.Exception and I couldn't figured out how
to access the Python properties in this "MyException".
