Re: [boost] BPL: Easiest way to return a private vector<long> ?

Why not just wrap std::vector<long> and provide the appropriate sequence
operations?

boost/libs/python/example/simple_vector.cpp has an example.

Ralf, it looks to me like getitem() in this example should use at() or some
other way of raising an IndexError when the index is out-of-range.
Otherwise, you won't be able to write "for x in v:" without the program
crashing(!).
