> Did I miss something? Yep, what you are missing is that the rule is really: (defparameter ("," defparameter)* "," "/" ["," [parameter_list_no_posonly]]) \| (parameter_list_no_posonly) which means that is either defparameter ("," defparameter)* "," "/" ["," [parameter_list_no_posonly]] or parameter_list_no_posonly and for the def(a): pass case the corresponding rule is parameter_list_no_posonly (check the rest of the specification). Do you think that adding these explicit parentheses would help with help making this more clear?

> Did I miss something?

Yep, what you are missing is that the rule is really:

(defparameter ("," defparameter)* "," "/" ["," [parameter_list_no_posonly]]) | (parameter_list_no_posonly)

which means that is either 

defparameter ("," defparameter)* "," "/" ["," [parameter_list_no_posonly]]

or

parameter_list_no_posonly

and for the def(a): pass case the corresponding rule is parameter_list_no_posonly (check the rest of the specification).

Do you think that adding these explicit parentheses would help with help making this more clear?
