Scala declare multiple variables at the same row with the first character as upper-case

Question

I'm trying to declare variables through tuple-assignment, such as:

val (hi, bye) = ("hi", "bye")

And obviously this is fine. However when having the first character as upper-case, the compiler explodes and complains about these variables not being already defined.

val (Hi, Bye) = ("hi", "bye")

Why doesn't this work? I'm running Scala 2.11.

By the way this works (as expected):

val Hi = "hi"
val Bye = "bye"

From here:

The tuple on the left-hand side is a pattern; names starting with capital letters are treated as constants when occurring inside a pattern. These constants must exist as values in the context. You find the exact semantics in the Scala spec under pattern matching.
