From my lazy user perspective, having masked and non-masked arrays share
the same "look and feel" would be a number one advantage over the
existing numpy.ma arrays. I would like masked array to be as transparent
as possible.

If the idea of having two payloads is to avoid a maximum of "skipna &
friends" extra keywords, I would like it much. My feeling with my small
experience with R is that I end up calling every function with a
different magical set of keywords (na.rm, na.action, ... and I forgot).

My 2 lazy user cents...
