On a personal note I'd like to congratulate my professional acquaintance Örjan Lundberg and his fellows Olle Kullberg and Viktor Klang for finalizing the Scala introductory book "Ett första steg i Scala". It's to my knowledge the first Swedish book to explain the concept of the Scala language.
You can find it at: http://www.studentlitteratur.se/o.o.i.s?id=2474&artnr=33847-01&csid=66&mp=4918
Congratulations guys! Hope I get the chance to read it soon!
