v1, v2 += inc1, inc2 please matches the pattern for multiple assignment already present .. isn't the EBNF at https://golang.org/ref/spec#Assignments currently wrong - in that it allows what is currently disallowed .. the correct would be (roughly) Assignment = ExpressionList "=" ExpressionList Assignment_operation = Expression assign_op Expression I see the follow on text corrects and clarifies this, but maybe it would be better to just split the EBNF def into two lines -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
