Hi Chuck,
I think I let my frustration get the better of me, and the message

I truly would like to understand where you're coming from on this,
though, so I'll try to make this more productive. My summary of points
that no-one has disagreed with yet is
Hi,
Thanks you very much for your lights !

One inconvenience I have run into with the current API is that is should be
easier to clear the mask from an ignored value without taking a new view or
assigning known data.
AFAIR, the inability to directly access a mask attribute was intentional to

Hi Mark,
I went through the NA NEP a few days ago, but only too quickly so that
my question is probably a rather dumb one. It's about the usability of
bitpatter-based NAs, based on your recent post :

Hi all,
I've been thinking a lot about the masked array implementation lately. I
finally had the time to look hard at what has been done and now am of the
opinion that I do not think that 1.7 can be released with the current state of
the masked array implementation *unless* it is clearly
