Hi all, I am doing some research to use boost-signals library.
I was reading the Tutorial of boost-signals library and have tested the
Documents-View example , and understand the basic to use it.

In the tutorial , there is a template function named  visit_each  , I
suppose it is a iteration function to iterate all the slots or signals .
However, there is not much information about how to use visit_each. I try to
look into source code but as a newbie in template programming I really could
not understand the source code.

I wonder the creator of signal library have done some update on the tutorial
and add in example on visit_each or other new interface/function

Besides, apart from what mentioned in the tutorial, what are the benefit if
a class is derived from trackable  ?

Sorry if my question are a bit weird.
