How to make order optional with Moor file query?

[CDDelta]

I have this query defined in a .moor file. How do I make the $order term optional for callers?

allDrives ($order):
    SELECT * FROM drives
    ORDER BY $order;

I've tried making $order = NULL but get the error This placeholder has a default value, which is only supported for expressions.

This is not currently supported, you'd have to pass something like OrderBy([OrderingTerm.asc(Constant(1))]) to ignore the order by. I can look into default values for ORDER BY too, feel free to open an issue for that.
