It nicely solves the issue of wanting to be able to easily check conditions 
which aren't strictly booleans without having to cast to bool (as is _very_ 
common to do in C++) while avoiding all of the pitfalls that implicit 
conversions give you everywhere else. So, it _is_ a bit confusing without a 
full explanation, but it's definitely a solid solution as far as usability goes 
IMHO.
