AFAICT, these are not usable for many (most?) Boost classes. These
visualizers are statically-typed; we need template-like visualizers.
Sure it might be possible (haven't tried) to visualize each
instantiation, but this is far from practical. Or am I missing
something? After all, Microsoft themselves are visualizing STL classes
using autoexp.dat, so I guess we're doing it right :-)

Also, I think that the visualizers we've created so far are quite
satisfactory, so I don't know why would you want anything more "advanced".

Did you read the discussion "[Boost-users] [multi_index] MSVS 2005
visualizers?" at the boost-users mailing list, BTW?

Thanks for the links anyway, I haven't tried writing a "DLL" visualizer
yet. We might use it for some Boost classes, such as ptime. However, we
must first examine how does it integrate with the IDE (whether it works
in the watch window, etc.). It might be that this feature no longer
works in new VS editions, as there is a brand new visualizer API for CLR
