I think it's the general rule that all indexing expressions have an invisible "..." on the right edge. For example, x[i][j][k] is an inefficient and IMO somewhat confusing way to write x[i, j, k], because x[i][j][k] is interpreted as: -> x[i, ...][j, ...][k, ...] -> x[i, :, :][j, :][k] That this also applies to newaxis is a little surprising, but I guess consistent. -n -- Nathaniel J.
