Is there a way or is there any module that
test the uniformity of the array by its elements.
So the returning TRUE only when every element of the
array is exactly the same (uniform). Here is the example:
@array1 = qw (A A A A); #Returns 1 /True
@array2 = qw (A B C); #Returns 0 /False
@array3 = qw (A A B C); #Returns 0 /False
