      According to a discussion on Freenode/#qt-labs on 09042018 1428 CEST:

      • http://doc.qt.io/qt-5/qtconcurrentmap.html <- the lambda example does not compile

      • the error is it can't convert QFuture<void> to QFuture<QImage> or whatever result_type is

      • it only works if you wrap the lambda into a std::function<T(T)>

      Known issue:

      even with the bug being open for 5 years, at least the docs should have working
      examples
