How to add an item to an instance of mutable.DoubleLinkedList[] in Scala?

Question

val list = new mutable.DoubleLinkedList[String]
list.add("foo")

This obviously cannot be compiled. How to fix this?

I spent some time with scaladoc, but it seems like the information on how to add an item to a list is a secret. Yes I am relatively new to scala and by the way I am completely frustrated with "syntax sugar" like :+, ++ and :::. It improves neither readability nor writability.

Technically :+, ++ and ::: are not syntactic sugar. ::: is motivated for performance reasons and :+ is priceless in match statements. — wingedsubmariner

DoubleLinkedList is deprecated, use ArrayBuffer.

val list = new scala.collection.mutable.ArrayBuffer[String]
list += "foo"
