Thanks a bunch 👍

[srenatus]

Could you please see after the DCO signed-off-by line? Details

[mmzeeman]

Like that?

[srenatus]

Exactly. Thanks!

🤦 I've put a typo in the commit message when giving it a small copy-edit. Sorry about that.

[mmzeeman]

Ah, such is life.

BTW... I also think there is an error in the infix-expr rule... The current form does not allow assignments like something := true or something_else = false.

Is there a grammar somewhere?

[mmzeeman]

This rule also does not make any sense.

ref = ( var | array | object | set | array-compr | object-compr | set-compr | expr-call ) { ref-arg }
