...or use
https://github.com/Kitware/qtextensions/blob/master/core/qtEnumerate.h.
Rather than returning a pair (which may add overhead), it creates a
proxy that just returns the iterator, so you can write:

  for (auto i : qtEnumerate(my_hash))
    do_stuff(i.key(), i.value());

As a plus, `key()` and `value()` are much more readable than `first` and
`second`.
