[Boost-users] bool_testable / safe bool idiom

What ever happened to bool_testable or some other answer to the safe bool
idiom?  I followed archived emails for a while, but thought it best to just
bring up anew.  Is a general solution not possible?  How about a couple of
solutions, where you pick the right one for your case?  Or a solution with
variations that you pick (policy based)?

Anything?

Thanks,
Tony
