Welcome to Scala version 2.10.0-M5 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_32).
Type in expressions to have them evaluated.
Type :help for more information.

scala> val n = 10
n: Int = 10

scala> "Bob is " + n + " years old"
res0: String = Bob is 10 years old

scala> "Bob is $n ears old"
res1: String = Bob is $n ears old

scala> s"Bob is $n ears old"
res2: String = Bob is 10 ears old

scala> s"Bob is ${n} ears old"
res3: String = Bob is 10 ears old

scala> f"Bob is $n%03d ears old"
res4: String = Bob is 010 ears old

scala> val hello = "Hello, World!"
hello: String = Hello, World!

scala> implicit class XMLinterpolation(s: StringContext) {
     |   object xml {
     |     def apply(exprs: Any*) = <span>{exprs}</span>
     |   }
     | }
defined class XMLinterpolation

scala> xml"<span>$hello</span>"
res15: scala.xml.Elem = <span>Hello, World!</span>

better still, try this:

implicit class XmlHelper(val sc: StringContext) extends AnyVal {
def xml(exprs: Any*): scala.xml.Elem = {exprs}
}

update: unfortunately i can't write the xml tags in this post, only in the gist file. but works exactly as in your original code, only that it doesn't create a class.
