Which scala mutable list to use?

Question

This is a followup question to No Scala mutable list

I want to use a mutable list in Scala. I can chose from

• scala.collection.mutable.DoubleLinkedList

Answer 1

I just want to use a list that I can add things to on the back.

Then choose something that implements Growable. I personally suggest one of the Buffer implementations.

I stay away from LinkedList and DoubleLinkedList, as they are present mainly as underlying implementation of other collections, but have quite a few bugs up to Scala 2.9.x. Starting with Scala 2.10.0, I expect the various bug fixes have brought them up to standard. Still, they lack some methods people expect, such as +=, which you'll find on collections based on them.
