Re: [Boost-users] [boost-users][bind/lambda] how to

I think what you're after is documented here:
http://www.boost.org/doc/libs/1_35_0/libs/bind/bind.html#nested_binds

Here's my attempt (though I haven't got access to a compiler atm):
function1<bool, Outer*> func = boost::bind(&Inner::good,
boost::bind(&Outer::inner, _1));
find_if(outers.begin(), outers.end(), func);

Hope that helps!
