Just as a side note, this is not a 'learn Scala' class. This is learning functional programming using Scala as the functional language. So, you won't get a lot of info on how Scala's complex type system works. But, this would be a great class if you are not familiar with functional languages (or what functional means). The functional aspect is very easily transferrable to other functional languages as the application is very close in all other functional languages (just as imperative OO language semantics such Java, C#, Ruby, Scala etc. are easily transferred).
It's true that this is not primarily a "learn Scala" class; we will concentrate on the purely functional subset. But types won't be omitted. We will focus on Scala's type system in week 4 of the class.
I just wanted to take this opportunity to let you know that I find the course content to be extraordinarily well designed. The lectures seem to hit all the right notes at the right moments, the homework is exercising the right muscles, and the grading does an excellent job of guiding us towards good test-driven-development and away from mutable state, etc.
