I think that is an over-simplification. The argument unpacking was handy in a number of situations where *args wouldn't suffice: lambda (px, py), (qx, qy): ((px - qx) ** 2 + (py - qy) ** 2) ** 0.5 IIRC, the original reason for the change was that it simplified the compiler a bit, not that it was broken or not useful. I'm not sure if that's applicable or other issues arise with:

def fn(*p): px,py,qx,qy = p; return ((px - qx) ** 2 + (py - qy) ** 2) ** 0.5

Thanks in advance! Francis
