Well, that's nicer in case 'at' has non-constant complexity. Still, I 
find this "surprisingly brutal".

Can you give me a vague idea of this technique's performance 
(seconds/functions), if recognizable at all ?

Oh! Use it already. My concern was about the preprocessed code (becomes 
huge, causes numerous template instantiations when used and in some way 
obscures the preprocessed headers).

However, if it works for Boost.Python I'll call it "common practice" and 
just use it ;-).

Thanks,

Tobias
