These 'look how these 4 lines of Java translate into 2 lines of Scala' don't really convince me to start using it. It would be a nice to see a more structural example. Like a real world app. Anything available that is open source?
I've been considering having a look at Scala as the next potential language that I'll learn.<p>It looks pretty nice. I'd add another point to the article - what I've seen of the community from mailing lists and such has been very positive. It seems like they're all (or mostly) very smart and welcoming.
Scala is not only means [A Ladder; Stairs],
But also A Rock, in Slavic languages...
And Marin (the creator of Scala) has polish last name,
and most probably is polish..
