I encountered the following behavior, which surprised me (even though it follows from the strict definition of Nub in the dictionary): ~. 1 _. 2 1 2 So it appears that Nub not only removes duplicates, it removes all indefinites as well. >From this, it is reasonable that: $= , _. 0 1 However, if one uses an atom (which should produce the same result), one sees this: $= _. 1 1 = _. 1
