Can you provide a list of objects that needs to be disposed in SharePoint?

Question

I need a list of SharePoint objects which need to be disposed.

This is for code analysis purpose. I have got a code review today and want a quick list of the objects to look out for in the code.

UPDATE Here is what to dispose and what not to dispose, if there is anything more to add then kindly advise:-

SPC110211: Dispose SPSite created by SPSiteCollection.Add

SPC110212: Dispose SPSite created by SPSiteCollection[] index operator
