Inheriting classes from std::

Question

There are many similar questions and I found both pro and against reasons to use this pattern so I am asking this here:

I think it is actually better to wrap it within your own class (i.e. proxy using std as member) since it makes it much more loosely coupled and if you would like to use a different data structure it would be quite easy, since you could simply modify your own class while the std classes should not be modified at all. If the interface of your objects is simple, maybe you should even implement your own interface (to make it easily compatible when you want to use a different data structure from std or boost or whatever suits your needs). Your current implementation is maybe not the best one at mentioned in the comments, but i would still recommend wrapping std uses in your own class (especially in larger applications).
