True, although that feels like iterating over the data twice for no
reason, which feels a bit weird.
In my case, I want to create a masked array, it would be nice to be able
to do that straight from a list, rather than having to turn the list
into an array and then turning the array into a masked array.
If I'm off base on this, let me know :-)
