Type annotations make the pretty-printed tree quadratically large

[nicolasstucki]

class Foo {
  val x: Int = (1: @annot1 @annot2 @annot3 @annot4 @annot5)
}

class annot1 extends scala.annotation.Annotation
class annot2 extends scala.annotation.Annotation
class annot3 extends scala.annotation.Annotation
class annot4 extends scala.annotation.Annotation
class annot5 extends scala.annotation.Annotation

types the code as

result of Foo.scala after frontend:
package <empty> {
  class Foo() extends Object() { 
    val x: Int = 
      1: Int(1) @annot1: Int(1) @annot1 @annot2: Int(1) @annot1 @annot2 @annot3
        : 
      Int(1) @annot1 @annot2 @annot3 @annot4: 
        Int(1) @annot1 @annot2 @annot3 @annot4 @annot5
  }
  ...
}

where we should have

val x: Int = 1: Int(1) @annot1 @annot2 @annot3 @annot4 @annot5

The pretty-printed tree is quadratic but is the actual raw tree that way too?

[nicolasstucki]

You are right. There is one tree per annotation.

We should still fix the printer
