I kind of feel like, if something would be confusing like this, maybe the 
compiler shouldn't be making an automatic decision. Not "just one more" 
match level, but just...don't match. If there are multiple matching 
overloads, just error out. Don't try to be clever and surprise people, 
just tell the user to be more explicit.
