Hi all, I keep running into problems trying to extend Pig due to variables being declared private. The latest time around it was in PigSlice -- one can't inherit it and do much meaningful overriding of methods because the input streams are private rather than protected, so I can't change how it gets created. I wound up having to copy+paste the class wholesale, which is unfortunate. I know the Slice/Slicer interfaces are going away, but as a general rule -- can we be mindful of folks trying to extend classes, and make inner members protected, rather than private or package?
Thanks -Dmitriy
