How best to venture into the land where square brackets fail?
I want to concatenate some 3D data cubes into a 4D dataset.
(Basically this is a cube of images produced as I vary two
parameters in a simulation). Square brackets don't work.
Is there any more elegant or faster solution than just a
for loop wrapped around
bigarr[*,*,i,j] = littlearr[*,*]
?

In particular it would be nice to be able to append an entire
3D 'slice' to my 4D data cube without having to re-allocate
a new larger array and copy everything over, but that's probably
not easy to do, is it?
