Python's standard library has (to take three examples) threads, processes, and
datetime functions. Meanwhile, PyQt has QThread, QProcess, and QDateTime.
Does this redundancy exist for C++ programmers who are programming Qt directly,
and who may lack a standard C++ library with these features?

If someone says "but

suspect much of the program code resides there.
