While initially I found it surprising, after reviewing Quote and Quote like Operators and a few tests with use re qw(debug All), I came to the conclusion that it is merely not obvious and wouldn't be inclined to call it a bug. Some examples in perlop to clarify what empty means might be helpful, and sufficient from my point of view.
