Basically, I see no advantage to comparing to a boolean literal. If the variable is not a bool, and you want to be explicit about it, then compare with an appropriate value (e.g., zero), or call an appropriate named function (e.g., use the fail() member function of an input stream instead of relying on an implicit conversion). In that sense, I see some value with comparing a pointer with a null pointer constant.
