bool_testable<> in Boost.Operators looks promising.

The reference mentions that:

bool_testable provides the antithesis of operator bool, such that the expression if (!p) is valid, whilst also making operator bool safer by preventing accidental conversions to integer types. ... bool_testable<> prevents these accidental conversions by declaring a private conversion operator to signed char, and not defining the body.
