The most concise, I guess, is:
static const auto laterDeleter = std::mem_fn(&QObject::deleteLater);
std::unique_ptr<QObject, decltype(laterDeleter)> a(nullptr, laterDeleter);
In C++17, if I don't mistake, you won't ned explicit type specifier in the
template, so it shortens to:
std::unique_ptr<QObject> a(nullptr, std::mem_fn(&QObject::deleteLater));

c++ has gone too far with its templates...
