sourcecode.Text applied to infix operator works unintuitively.

[pocorall]

class MyBuilder {
  val builder = new StringBuilder

  def add[T](txt: sourcecode.Text[T]): MyBuilder = {
    builder append txt.source
    this
  }

  def +[T](txt: sourcecode.Text[T]): MyBuilder = {
    builder append txt.source
    this
  }
}

val hello = 3
val world = "hi!"

new MyBuilder().add(hello).add(world).builder.toString() // equals to "helloworld"
(new MyBuilder() + hello + world).builder.toString() // equals to "hello + worldworld"

I hope that .add(hello).add(world) and + hello + world make the same result.
