Consider the following code

#include <QDateTime>

struct Foo {

    QDate someDate() {
        return {};
    }
};

int main(int argc, char *argv[])
{
    Foo *foo = new Foo;
    QDateTime{foo->someDate()};
}


clazy warns that the QDateTime ctor is deprecated and suggests to use QDate::startOfDay()

The fixit generates:

foo->startOfDay();

while it should be

foo->someDate().startOfDay();
