Auditorium

9.30 Tuesday Keynote

Josh Suereth, Dick Wall, Auditorium

Josh and Dick will take a deep dive into one of Scala's more advanced language constructs: the for expression. In this coding-example-heavy talk we will cover topics like:

• For, it's not about looping

(executive producer of the movie, and I didn't even know it... clever huh?)

please, please, please - If you know of any slides/code/whatever not on here, then ping me on twitter or comment this Gist!

This gist will be updated as and when I find new information. So it's probably best not to fork it, or you'll miss the updates!
