True, declaration of foo should be changed from type bool to int too. Since as I can see this could cause a lot of problems, shouldn't be there only a warning without fixits?

Same type error as earlier, should a fix be applied (changing the type of the parameter in template definition would be unlucky too, maybe a wrapper function which could be passed to doSomething2() and does the conversion) or only a warning?
