In my current project, there are a lot of code fragments that read like this:
result->insert( "positions", positions_.begin(), positions_.end(), bind( &Position::serialize, _1, boost::cref( locale ) ) );
The scheme is always the same, all that varies is the name of the serialized class. Thus I wanted to write a helper:
result->insert( "positions", positions_.begin(), positions_.end(), serializer< Position >( locale ) );
But the problem is, that AFAIK I have no (documented) way to specify the result type of such a helper function. The syntax I would imagine basically looks like this:
template< typename T >
typename Bind< &T::serialize, _1_type, boost::reference_wrapper< const Base::Locale > >::result_type
serializer( const Base::Locale& locale ) { return bind( &T::serialize, _1, boost::cref( locale ) ); }
Is something like that possible? I hope so, but I guess I'm not the expert to understand all the details involved in the bind-internals. The above is just an idea, of course it might look different in practice. The question is, whether we can create some mapping between the call of the bind-function and a provider for the result type that users can understand without looking into the code of bind itself.
