Yes, it is intentional.  A change was introduced in slang version
pre1.4.6-15 such that if A and B are arrays, then the array [A, B]
is a 1-d array composed of the elements of A and B.

With that change, a and b are equal.

It should be, but unfortunately it is not aside from the changes.txt
file.

A useful alternative is to use a list of arrays, e.g.,

  A = [1:100];
  B = [200:400];
  L = {A, B};
