Phobos 'collections' question

[Robert McGinley]

Hey all,
Mostly as an exercise I'm considering writing an ArrayList, AVL tree, and 
possible other standard data structures in D.  I have two questions.
1.) If completed should I send these around for review and inclusion or do they 
not belong in phobos?
2.) If I'm working on including these in phobos should I put them in 
container.d (that has RedBlack Trees and a Singlelinked List) or is there a 
better location?
