[Boost-users] converting value before inserting into a list

I want to convert values according to a map before inserting it into the 
list. What is a proper way to do that?
I have this:

map<int,int> m;
vector<int> a,b;

for(vector<int>const_iterator i=a.begin();i!=a.end();++i)
        b.push_back(m[*i]);

I could use std::copy with std::back_inserter to add elements to b, but 
how do I convert it first? Should I write my own version of 
back_inserter for that?

copy(a.begin(),a.end(),my_back_inserter(b,m));

Thanks.
