I've mentioned this thought off-list already but let's discuss it
officially:

A fear I have is that this makes empty more looking like a function,
while not being one. Right now one notices quite quickly that it is
something else. Things like $check = $condition ? "empty" : "isset";
$check($bar); trigger an even more confusing error (Call to undefined
function)

I'm not sure whether that's a strong argument, but I guess it's good
enough to be noted :-)
