It's a more concise way of writing:

You can do this in C/C++ as well (and presumably some other

Hmmm... thinking about it, it does make perfect sense. The

In the documentation one can learn how to do array operations
with 1D arrays. However, this does not scale up for 2D arrays.
For example, the following does not work:

a = [[1,1],[1,1]];
b[][] = a[][]*2;
