I was about to suggest that perhaps this is how it should be interpreted 
;-).

Perhaps it is too much to use syntax to indicate whether positional args 
should be silently ignored or raise an exception.  Given

def f(*ignored, a, b='yes'): <body>

positional args will be ignored if 'ignored' if never referenced again.  To 
raise an exception, just add

  if ignored: raise TypeErrror("Positional args not allowed")

Given that keyword only functions should be fairly rare (given that we have 
survived thus long without), is a syntactic abbreviation needed?
