For what it's worth, my experience learning Scala's type system was:

- plain old (nominal) types: easy, same as Java

- type parameterization: also easy, same as Java, but with square brackets instead of angle brackets. I felt square brackets looked a lot nicer, and probably was therefore easier to read, too.

- function types: functions in Scala have nominal types like anything else, with a type parameter for the result type and one each for the parameter types. But there's also a shorthand syntax. Instead of Function1[String, Int], for example, you can say String => Int. The latter is actually easier to read, but when combined with an assignment such as "val a: String => Int = something I find it can sometimes be non-obvious at first glance how to parse it.

- traits: traits were quite easy for me to understand and use. They are exactly like classes except they can't (currently) take constructor parameters and the meaning of super is different inside them. Mixing in multiple traits is straightforward, as i
