This is a bit more tricky than expected because we support passing references to objects that are into the list itself (for instance, list.removeAll(list.front())). For those objects we have to take copies. This is fine, but the moment we make the function generic, that's going to fail when passing arguments of types that cannot be copied, such as arrays (e.g. stringList.removeAll("hello")). For those, keep a reference, as they cannot be aliases into the list anyhow. [ChangeLog][QtCore][QList] The removeAll and removeOne methods now take an object of any datatype -- and not just the list's own value type. This allows for heterogenous removal inside QLists.
