 If the syntax ``*expression`` appears in the function call, ``expression`` must
 evaluate to a sequence.  Elements from this sequence are treated as if they were
-additional positional arguments; if there are positional arguments *x1*,...,*xN*
-, and ``expression`` evaluates to a sequence *y1*,...,*yM*, this is equivalent
-to a call with M+N positional arguments *x1*,...,*xN*,*y1*,...,*yM*.
