In CPython 3.4 this raises a SyntaxError. In CPython 3.5+ having a positional after * is allowed but uPy has the wrong semantics and passes the arguments in the incorrect order. To prevent incorrect use of a function going unnoticed it is important to raise the SyntaxError in uPy, until the behaviour is fixed to follow CPython 3.5+.
