[Numpy-discussion] Indexing by label in 3rd dimension

I have an array *mask* of shape (a, b) and another array *intensities*
of shape (N, a, b), where the values in *mask* range from 0 to N-1. It
is somehow similar to label arrays in scipy.ndimage.
Now I want to pick those entries from the first dimension of
*intensities* which are given by *mask*. The returned array shall again
wave shape (a, b).
Can this be done with fancy indexing?
