I should have said is that I did not baseline at all off of Signals or
Signals2. I did peruse
through them while I was searching for examples of Signal and Slots. I
did like what I saw;
however, my thought and intention was how to make a variadic template
version of what I
was seeing. So in effort what I created was a proof of concept, not a
full fledged
enhancement of Signals or Signals2. Once I had success, I thought it
would be fun and interesting
to see if I could help implementing this through Boosts Signals if it
was desired.

And less code to maintain! :P
