|Subject:||PPI::Node::find returning empty string?|
This is borderline wishlist, but... Although I can see the virtue in having PPI::Node::find's value being a valid boolean when used in such a context, it was not my first expectation. I had to look up the function documentation to find out why it was returning an empty string. My expectation was that it would instead return a reference to the empty list if there were no results matching the search criteria; I think that would be a more common intuitive expectation. I realize it probably isn't something that can be changed at this point, and that you might not want to anyway, but that it was at least worth speaking up about.
