I'm looking at all these "operator unspecified_bool_type"s in Boost. They vary:

It's hard to get all of these right, and various Boost libraries have made changes in the past that got it wrong: type-safety compiler workarounds zero runtime overhead (a.k.a. more compiler workarounds)

At some time, there was a safe-bool thingy in Boost.Operators, but it was removed. I honestly do not know why.
