Specialized method to `map` over an `ArrayPartition`?

[jonniedie]

map over an ArrayPartition is slower than mapping over the inner partitions and reconstructing an ArrayPartition. I typically use something like:

partition_map(f, array::ArrayPartition) = ArrayPartition(map(partition -> map(f, partition), array.x))
partition_map(f, array) = map(f, array)

Would it be worth making this the default for map over a single ArrayPartition?

Yes, that would be a good default.
