Both should definitely be there.

I think I prefer forcing users to be specific about what they do, in
this case to point out that they are not just setting a value but also
possibly signalling receivers. On the other hand, enabling these two
features would allow users to treat this class as a regular value in
generic programming. Which do you think is better?

I did, but I wanted to point out that I was using signals and slots.
Observable would be great if it was in the namespace boost::signals.
Do you think this class might be useful enough to be added to boost
slots and signals?
