Scala REPL is smart

Apparently the REPL is smart enough to figure out when you declare a function as it waits for the closing bracket to return. It auto-injects the | for you as you enter new lines. I read that there are a few use cases it can't handle very well yet like defining a class and companion object. Once I've tested this with current version of the REPL I will blog about these cases.

scala> def addTwo(x: Int) = {
     |    x + 2
     | }
addTwo: (x: Int)Int

scala> addTwo(5)
res5: Int = 7
