Ah, okay. Glad it's not a fundamentally hard concept. I don't know that I want to dig into actually implementing that, just now, but I've added myself as nosy on bug 2292 (which is where the patch is being discussed, and is referenced in the PEP). I don't have a major use-case for it in Python, though I've used the equivalent Pike feature all over the place (it's done as @args where args is an array, and it's equivalent to listing the args - pretty much the same as *args in Python) - it's handy, even though it's almost never really crucial. It's perhaps telling that the only time I can recall running into this with Python is in making some deliberately bad code :D ChrisA -- https://mail.python.org/mailman/listinfo/python-list
