Why do you have both a namespace and a "hetero" prefix? That's redundant.

I cannot imagine a use case for any of these. Rather than have a set of containers, each targeted to a specific data type, your interface uses one type that must be specialized in every use, including member function calls. The former does require naming each container, but that leads to more readable, simpler code in my mind.

Can you provide any motivating examples for using these containers which demonstrate their benefits over ad hoc containers?

This class seems to provide a little syntactical sugar over an any-based container, so I can imagine some benefit.
