There's a public PythonOps.CreateThrowable. It just forwards the call to the internal PythonExceptions.CreateThrowable. > > On a related note, there's too much stuff that's used in > IronPython.Modules but is internal in IronPython - it makes it hard to > figure out the "proper" (public) way to do things. Yeah, maybe we should remove the internals visible to and make everything it relies on public. I think I'd be mostly alright with that but there might be a few places where we suffer (like not having access to our AddNoLock methods for appending to lists). _______________________________________________ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
