Is there a safe bool idiom helper in boost?
boost, c++, safe-bool-idiom
Solution
`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.
Problem
25% of programmers work time is spended by checking if the required code already exist. I'm searching for a base class for implementing the safe bool idiom.
