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.

Which leads to 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... Best, Pierre
