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

-

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

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

and fine. when having first character upper-case, compiler explodes , complains these variables not being defined.

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

why doesn't work? i'm running scala 2.11.

by way works (as expected):

val hi = "hi" val bye = "bye"

from here:

the tuple on left-hand side pattern; names starting capital letters treated constants when occurring inside pattern. these constants must exist values in context. find exact semantics in scala spec under pattern matching.
