Re: [boost] safe bool operator

It enables a one liner implementation for a safe_bool operator:

class my_class { public: bool some_is_valid_function() const; operator boost::unspecified_bool_type() const { return boost::make_safe_bool( some_is_valid_function() ); }

Using a single type allows unrelated classes to compare equal with operator==.
