Yeah, sounds like a nice feature. I will make a mark in my todo list.
Before I could tackle that I would need to overcome my template
instantiation issue. I cannot even compile with MSVC 7.1. It's
complaining:

 fatal error C1055: compiler limit : out of keys

I think I need to seriously rethink the design.

Not sure if I follow here.

Thanks for your input,
