New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>: The syntax f(x for x in [1],) is ambiguous and reasons that allow it (omitting parenthesis in generator expression and using trailing comma in call expression) are not applicable in this case. Rationales see on Python-Dev: https://mail.python.org/pipermail/python-dev/2017-November/150481.html.
