Ilya, thank you for chiming in. Much appreciated. I am not exactly sure I
understand. What are the "large number of known problems"? Your reference of
operator_bool.hpp does not strike me as such. Do you have anything in mind that
was not mentioned in the chapter 7.7 of Alexandrescu's "Modern C++ Design"
or/and the article at http://www.artima.com/cppsource/safe_bool.html by Bjorn
Karlsson?

I glanced over "explicit conversion operators" in C++0x. It did not struck me as
relevant to safe_bool. Care to elaborate?

Best,
V.
