Some folks don't like iostreams, I keep using them, since Turbo C++ 1.0 for MS-DOS.

Although I would probably use std::print in more modern compilers.

D needs to work into its marketing, all key features that made it relevant back in 2011 with Andrei's book have now been copied even if badly, across all mainstream languages.

I thought it was ugly in 1987, and it hasn't improved with age. Then < > for templates made it worse.

Then there's formatted I/O:

    void IOS_precision()
    {
    cout << "\n--------------------------\n";
    cout << "Implementing ios::precision\n\n";
    cout << "Implementing ios::width";
    cout.setf(ios::fixed, ios::floatfield);
    cout.precision(2);
    cout<<3.1422;
    cout << "\n--------------------------\n";
    }

and I don't know if the problem with multithreading was resolved or not.

Any program can be written in any language. But why suffer?

That is always given as an example of how bad it is, yet I seldom have used any kind of such formatting since 1993.

iostreams hardly played a role in all C++ GUI frameworks and for object serialisation, precision flags were seldom used.
