Yes, it is more supporting data that we need a reusable bool conversion
mechanism. I am finding that I need this in Boost.Range (since the
implementation in here is sub-optimal). I am also finding in my other
application development that a general utility for providing such a
mechanism would be extremely useful.

I intend to develop such a reusable Boost-ified macro and get it into the
core of Boost.

Any objections, or comments?
