Thanks! Here is an implementation: https://bugs.python.org/issue32012.
I have found that formally trailing comma after generator expression is
not allowed by the grammar defined in the language reference:
call: `primary` "(" [`argument_list` [","] | `comprehension`] ")"
But the actual Grammar file contains different rules.
