I'm just as weary of persistent containers of mutable elements using GC. 
It doesn't make a difference.

The English language has a word I like a lot: "unassuming". I'm not sure 
about its etymology, but a nice theory is "a person who doesn't assume 
bad things about others".

I'm glad to hear about various pros and cons regarding these containers. 
Slinging this kind of stuff is unlikely to further the dialog.
