Is there a name for this kind of assignment? See how 'n' is assigned below.

Assignment.scala

scala> case class Name(name:String)
defined class Name

scala> val a = Name("Anoop")
a: Name = Name(Anoop)

scala> val Name(n) = a
n: String = Anoop

scala>

I don't think it has a name for the assignment itself, it's just "using the Name extractor".
So an idea would be "Extractor assignment" but that sounds weird IMHO.

Either ways, this is very interesting. I noticed this is possible and got excited!.

:-)

worth mentioning is that it's the same thing which happens here:
a match { case Name(n) => ... }

Right. It makes sense. I was half expecting this to work,

    scala> val x*x = 16
    <console>:21: error: not found: value *
           val x*x = 16
                ^

    scala>

but then, now I know!.
