What wrong with that? Other than item 3? I would consider this as a
useful feature allowing to pass container in old function expecting

I would not say that it is more dangerous that s = new T, but you
agreed to live with that.
There are al least 2 significant(?) drawbacks with private
1. Need to forward all the functions
Now it's about 70-80 persent of all function you implemented.
2. Can't use custom function.
Since you forward only some functions you can't use any custom
function presented by base contaner. For example map::find, or any
custom function in my custom container.
