This week in #Scala (18/01/2013)

Posted by Chris Cundill on Fri, Jan 18, 2013

Welcome to another edition of #ThisWeekInScala.

Firstly, you will be interested to know that Martin Odersky is starring in a musical. So you knew he was a smart guy who invented a certain cool language, but did you know he could sing?

Secondly, people have begun playing with the new features in Scala 2.10. Macros are powerful, no doubt. You know the old adage, with great power comes great responsibility. Well, @puffinfresh is taking his responsibility seriously:

@puffnfresh: #Scala macro naughtiness: turn all vars into vals.

Glad you're not on his team? Well, it get's scarier:

@puffnfresh: #Scala annotation macros and untyped macros are going to change a lot for me. Going to make my own type system with better inference.

Jokes aside, there's some great features in Scala 2.10 worth checking out. Like this guy found out...

@tpolecat: Spent some time playing around with string interpolation in #scala 2.10, and my initial skepticism was unwarranted. It's great.

Right, enough preliminaries, now onto this week's roundup...
