regexp_unpackaging.scala

scala> val s = "Me Moscow 2012"
s: String = some text 2012

scala> val PersonLocation = """(.+) (.+) (.+)""".r
PersonLocation: scala.util.matching.Regex = (.+) (.+) (.+)

scala> val PersonLocation(person, city, year) = s
person: String = Me
city: String = Moscow
year: String = 2012
