Encouraged by your and Stefan's suggestions, I've spent another day at
looking what the possibilities are.

1. I first created my own binary_?archive classes which inherited from
common_?archive. This resulted in pulling in the library with the
'behind the scenes type tracking'. It seems, inheriting from common is
not an option for me if I want 'zero-allocation' serialization.
Correct ? (I also tested the demo_fast_archive.cpp extended with
no_header, but that one also allocated).

2. I then tried to work further on Stefan's code snippet. It works,
but indeed only for 'primitive_type's. I *think* I need functionality
upto the 'object_serializable' if I want std::vector<T> as well. Since
Stefan's operator& consumes every T, I'll need one operator& for each
primitive type, and then an operator& that tries to save/load using
free functions of the not primitive type.

3. It looks that I'll have to implement the Archive concept from
scratch or at least based on Stefan's code and the
load_binary/save_binary code from binary_?archive.

Am I on the right track ?
