You can hack your way to it by means similar to the ones I used here

http://groups.google.com/group/boost-list/browse_thread/thread/2c91d43bb78ea2a1/a4a60b2e79af6c92

However, your case is slightly different.  In your case it shouldn't  
matter if Impl<A> and Impl<B> are given the same name, because there's not  
chance of mixing the two due to C++ typing rules.  I don't know if this  
works in the serialization library as it is, though.
