Someone should follow up my node: If you can determine which datatype is being "inserted" into your container, by checking the inheritance tree and by multi-inheriting a dummy class dictating the class type (node vs something else), you may come up w/ a cleaner implementation. You won't have these random methods in your datatypes-to-be-inserted that will make no sense out of context of the applicaiton.

In the end, you want a good cohesion, but loose coupling. Imagine if you took half of your classes and threw them in another project. Will those classes and their extra methods make sense elsewhere?

This doesn't easily apply to business-level classes, since everyone's business works different. :)
