So, if I got this right, you managed to sort-of-prove that a stack-based 
partial/nonstd::vector<> implementation is theoretically possible...what I 
fail to see is how does this, in any way, through analogy or otherwise, 
implies anything about the benefits of a stack-based vector...much less 
about the original or other proposals so far listed in this thread...

As one size does not fit all, 'I don't see myself' is not a valid argument 
of any kind...By your rationale you not only do not need/want a stack-based 
vector/array-like container (which was proposed here precisely because there 
are people that demonstrably need it) but for example also intrusive_ptrs 
(after all if shared_ptr is somehow causing performance problems we should 
'get down to the metal'/raw pointers)...should we have those removed from 
Boost? If not, what is the issue with including a new container in Boost 
that tries to solve a specific problem and that noone will force you to use?
