byKey and byValue: properties or methods?

[Kapps]

Is there even a point to having byKey/byValue?
Once UFCS comes in (and there's already a seemingly working pull request 
for it), having .keys return a range like byKey/byValue should will be a 
silent (though more efficient) change for most programs. And in the 
situations where it's not (namely when you want to store it as an 
array), just adding a .array at the end would work.
