Dear developers,
According to the Language Reference, a starred expression is defined
by
starred_expression ::= expression | (starred_item ",")* [starred_item]
https://docs.python.org/3/reference/expressions.html#expression-lists
However, in view of the definition of an assignment statement
assignment_stmt ::= (target_list "=")+ (starred_expression |
yield_expression)
https://docs.python.org/3/reference/simple_stmts.html#assignment-statements
I believe the correct definition actually used is
starred_expression ::= expression | (starred_item ",")+ [starred_item]
(that is, use "+" instead of "*").
Should it be fixed?
The existing definition states that 'starred_expression' could be empty,
so it does look suspicious.
