Some discussion of disk storage might also help. I don't see how the rules can be enforced if two files are used, one for the mask and another for the data, but that may just be something we need to live with.
It seems it wouldn't be too big deal to extend the *.npy format to include the mask.
Could one memmap both the data array and the mask?
This I haven't thought about too much yet, but I don't see why not. This does provide a back door into the mask which violates the abstractions, so I would want it to be an extremely narrow special case. -Mark
Netcdf (and assume hdf) have ways to support masks as well.
