An ordered map as the default AA implementation would be worse. Most use
cases for a hash map don't need ordering. Perhaps we'll have one in
std.container at some point, but as it stands I'm unaware of any
implementations out there. Neither the EMSI containers [1] nor
dcollections [2] has one that I can see.

I've contemplated adding one. I think it's a nice feature of php.
But note that red black trees are ordered if you need some sort of
ordering independent of insertion order.
