In a fresh Scala project, if I put the following into a worksheet I get an error:
var d = scala.collection.mutable.Map[String, Int]()
d("a") = 1
Seems like it's trying to print out a result for the map set and failing. Calling `update` works fine.
The same code works in the scala repl w/o a problem.
