[C++-sig] Exposing members of members

[Ricardo Abreu]

Hello,

Suppose that I have a class A with a member of type std::pair, called a. 
If I want to expose class A to python while allowing read/write access 
to the object pointed to by a.first, what to I put in def_readwrite?

I tried something like class<A>("A").def_readwrite("a", &A::a::first); 
but it doesn't work. Also been trying with boost::bind but didn't have 
any luck :s

I know I could do getters and setters, but there would be a lot of them 
because my "A" has a lot of members like "a".

Thank you in advance,
Ricardo
