     47 # Note that, in this case, the repeat operator makes little sense
     48 # and is NOT equivalent to requesting an array slice. In the case
     49 # of "print a1(1)@3", the size of each element in the array is
     50 # variable from element to element.  So, when asked to repeat
     51 # one element of the array a number of times, you're not guaranteed
     52 # to get the same answer as in a slice; while the slice will
     53 # take into account the array stride, the repeat operator uses
     54 # the size of the object being repeated as its stride, which
     55 # is often not the same. So, in the test below, the output for
     56 # the second and third element is not entirely predictable, because
     57 # it reads part of their contents from a memory region which has
     58 # an undefined value (the "holes" between the each actual element
     59 # of the array).
