The Tech Help You Need

I was going to update the wiki with the different ways to access/modify maps,
but I don't understand why the last line in this code sample fails:

val map = new scala.collection.mutable.HashMap[String, Any]
            
map("likes") = "cheese"
assume( map.get("likes") == Some("cheese") )
assume( map("likes") == "cheese")
      
assume( map.get("fakeKey") == None)

map += "name" -> "Gromit"
assume( map("name") == "Gromit")

map += "id" -> 1234
assume( map.get("id") == Some(1234) )
assume(map.get("id") == 1234, "map.get(id) == 1234 failed" )
