Interesting. Does it result in a compile error if you try arrays of different sizes? (If it's just a run time error, I don't see how it's different to implementing this with operator overloading in any language that supports it).

Sure, if you try with non conformable arrays, gfortran for example would tell you something like this:

  Different shape for array assignment at (1) on dimension 1

Note that a scalar is conformable to any array, so that A = 2 for example would work for any shape of A, and would fill A with 2's.
