By assigning to a scalar or by checking truthiness, you’re forcing a scalar context, so it can be expected to behave the same – that is, return a falsy value (0) when empty and non-falsy when not (and all the bucket counts are non-falsy). Same goes for arrays which report number of elements when not wantarray.
