The any in std.algorithm is defined:

I see that as very different from !empty.
But if you use a predicate that always returns true that would be basically the
same. At least for arrays.
int[] a = [];
assert(a.any!(e => true) == false);
int[] b = [3, 4, 5];
assert(b.any!(e => true) == true);
I don't understand why one would go around the horn to just check for !empty.
