Support for floor division operator (//) in Arithmetic Expansions?

Looking at Arithmetic Expansions I noticed the omission of a floor division operator. I was wondering if that was a conscious decision or if it might still be added in the future.

I have no strong feelings either way, but it seems to be a nice feature. It’s easy to make a floor division function:

fn floor_division dividend:int divisor:int
        let remainder = $((dividend % divisor))
        let dividend = $((dividend - remainder))
        echo $((dividend / divisor))

But it doesn’t seem possible to make it usable inside an arithmetic expansion. If it was possible it could turn this:

$(( ((dividend - (dividend % divisor)) / divisor) ))

Into this:

$(( dividend // divisor ))
