FAIR ENOUGH! Indeed in those cases -- flattening might be
required and the use of tools for transformations of such kind is
advisable (especially whenever masking is involved).
I guess I just saw way too many unnecessary uses of flattening whenever
data could have been manipulated in their native ND form thanks to
super-powerful broadcasting numpy supports.
