Question with peg_generator grammar

[HJX-001]

as per metagrammar.gram item can be optional

item[Item]:
    | '[' ~ alts ']' {Opt(alts)}

by this it can be concluded that alt can be optional and so on. As understood by me is that it is possible to write a rule like rulename: with no alts. pls clerify.

Since this isn't a bug, I'm going to close this.

[HJX-001]

well it is closable, but it can be a bug if this is not intended(only applicable to pegen part). and still correct grammar can be written but if its true why allow it in first place.

Oops, wrong button!

After asking on discuss.python.org, if this turns out to be a bug, please re-open this issue. Also, if you do post something there, please put a link to it here. I'd be interested in the discussion.

Thanks!
