Thanks for the link; very useful indeed.

Many thanks to Kay and Bruno for suggesting Boost; I browsed through
its numerous libraries and they're quite impressive ! They seem
indispensable, especially for python (or other very high level
language) programmers going back to C++. Some libraries that seem to be
very relevant to pythoneers are:

- any: brings dynamic typing in C++
- tuple; 'nuff said
- iterator: out-of-the-box equivalents of
itertools.{imap,ifilter,izip,count}, reversed(), and others not
existing or applicable in python
- tokenizer, string_algo and regex: similar functionality to str.* and
- bind, mem_fn, function, functional, lambda: first class callables,
currying, higher order (functional) programming
- assign: syntactic sugar through operator overloading for (relatively)
readable container initialization:
    map<int,int> next = map_list_of(1,2)(2,3)(3,4)(4,5)(5,6);
    is actually valid and equivalent to
    next = dict([(1,2), (2,3), (3,4), (4,5), (5,6)])
- many, many more goodies, with or without respective standard python
equivalent (threads, graphs, math utils, serialization,
metaprogramming, etc).
- and last but not least, Boost.Python. I don't think it's just a
coincidence that among all languages they chose Python to make
interoperable with C++ :-)

Thanks again,
