The effect for source and readability is that of a cast; yes it is not a 
call to asInstanceOf. I do not feel strongly though this would have been the 
righter way to write this code.

@srowen it wasn't really casting here. It's just an explicit type 
definition.

I know this is bikeshedding, but I very slightly prefer this change. 
Casting is uglier than using the 'right' method. I do understand "empty" is 
slightly less familiar.

Yeah, I wouldn't bother.  The way this PR does it is arguably better 
because it can be done consistently across all collections:
```scala
val l0 = List.empty[String]
val s0 = Set.empty[Int]
val o0 = Option.empty[Byte]
```
...but it's pretty trivial, and I don't buy the readability argument.

I'm actually not sure this is better in readability in either, since most 
people know about None/Some/Option, but not necessarily Option.empty (I didn't 
know about this before your pr).

No performance benefits but improves readability.
