We could use [] for matrices also I guess.
Then it will look the same as numpy.
It's useful to index vectors with [], since the code will be similar
for regular arrays.
I forgot something important, namely that operator[] expects exactly
one argument, so we can't do A[i, j] for matrices.
Maybe then it's better to have () both for vectors and matrices?
