Tuple parameter declaration and assignment oddity
In python I can do
>>> (a,b) = (1,2)
>>> (b,a) = (a,b)
>>> (a,b)
(2, 1)
But in scala:
Welcome to Scala version 2.8.1.final (OpenJDK Server VM, Java 1.6.0_20).
Type in expressions to have them evaluated.
Type :help for more information.
scala> var (a,b) = (1,2)
a: Int = 1
b: Int = 2
scala> (a,b)=(b,a)
<console>:1: error: ';' expected but '=' found.
(a,b)=(b,a)

So while I can initialise vars as a tuple, I cannot assign them as a tuple. Any way to get around this, other than using a tmp var?
