No of course that's fine! But it isn't really RAII to use ctors/dtors/assignment for 
memory management: that's what they're designed for and do well.

The problem is managing non-memory resources: file handles, sockets, etc.

I use RAII in some cases, for example it's nice to go:

void f() {
  mutex dummy;
  blah();
}

and have the mutex released on exit, even if the exit is an exception being
thrown from blah.

Indeed, for ZMQ messages, I was complaining that zmq_msg_init has
the wrong interface and semantics because I want to use it as a default
constructor. And put zmq_msg_close in the destructor.
