We could add a special value, let's call

sys.NULL, whose specific semantics are "turns into NULL when

Would it be better if it were called "__null__"?
No. The problem is not the name, the problem is in the semantics.
This would mean a permanent special case in Python's argument
parsing (and "special cases aren't special enough to break the
rules"), and would inflict these same awful semantics on alternate
implementations like PyPy, Jython, and IronPython.
