Ability to alias group expressions

SELECT month, COUNT(*) AS order_count

FROM orders AS o

GROUP BY DATE_PART_STR(o.order_date, "month") AS month;

This is a valid query in Analytics, but in N1QL I would have to write it as follows:

SELECT DATE_PART_STR(o.order_date, "month") AS month, 

    COUNT(*) AS order_count

FROM orders AS o

GROUP BY DATE_PART_STR(o.order_date, "month");

I don't like having to write the expression DATE_PART_STR(o.order_date, "month") twice--that's what aliases are for. Do you think that N1QL users would appreciate aliases in the GROUP BY clause, as in Analytics?
