[New-bugs-announce] [issue16319] optional comma inside function argument list triggers syntax error

[Inyeol Lee]

New submission from Inyeol Lee:

Ubuntu 12.04, python 3.2.3

Optional trailing comma causes syntax error if used for keyword-only argument list:

These are OK --
def f(a, b,): pass
def f(a, b=None,): pass

These triggers syntax error --
def f(a, *, b,): pass
def f(a, *, b=None,): pass

python 3.1 and 3.2 shows this error, not tested for 3.3 yet.
