I'm wondering what is the use for the ignored data feature?
I can use:
A[valid_A_indexes] = whatever
to process only the 'non-ignored' portions of A. So at least some simple cases of ignored data are already supported without introducing a new type.
OTOH:
w = A[valid_A_indexes]
will copy A's data, and subsequent use of
w[:] = something
will not update A.
Is this the reason for wanting the ignored data feature?
Suppose you are working with plotted data and want to turn points on/off by clicking on them interactively to see how that affects a fit. Why make multiple copies, change sizes, destroy data, and all that nonsense? Just have the click update the mask and redraw. Chuck
