(self, *args, **kwargs)
return self._from_args(args, is_commutative)
Create new instance of own class with args exactly as provided by
        caller but returning the self class identity if args is empty.

           This is handy when we want to optimize things, e.g.

               >>> from sympy import Mul, S
               >>> from sympy.abc import x, y
               >>> e = Mul(3, x, y)
               >>> e.args
               (3, x, y)
               >>> Mul(*e.args[1:])
               x*y
               >>> e._new_rawargs(*e.args[1:])  # the same as above, but faster
               x*y

           Note: use this with caution. There is no checking of arguments at
           all. This is best used when you are rebuilding an Add or Mul after
           simply removing one or more terms. If modification which result,
           for example, in extra 1s being inserted (as when collecting an
           expression's numerators and denominators) they will not show up in
           the result but a Mul will be returned nonetheless:

               >>> m = (x*y)._new_rawargs(S.One, x); m
               x
               >>> m == x
               False
               >>> m.is_Mul
               True

           Another issue to be aware of is that the commutativity of the result
           is based on the commutativity of self. If you are rebuilding the
           terms that came from a commutative object then there will be no
           problem, but if self was non-commutative then what you are
           rebuilding may now be commutative.

           Although this routine tries to do as little as possible with the
           input, getting the commutativity right is important, so this level
           of safety is enforced: commutativity will always be recomputed if
           self is non-commutative and kwarg `reeval=False` has not been
           passed.
