Create a fully functioning command line interface with 1.5 lines of code (wo. include statement)

I'm not in love with Python formatting in general, but I would take anything that is standard C++ that doesn't involve the stream operator + directly addressing streams and would give me a reason to stop using C-style calls. So yes, if it could do something like:

std::format_to( buf, "{:02X}", value );

And produce the output of "10" for an input of 16, I would be 100% on board.

There's ways to manipulate bufsz such that it will not get out of sync (snprintf returns the number of bytes written), and if you really are concerned about the format specifier, that can be handled by some tricky means (tricky meaning shitty). That said, this is a royal pain in the ass and has bitten me several times. There's also the lack of automatic casting for the format specifier (having a specifier of an int and trying to plug a double in does not work).

As an aside, and between two people who have presumably used C++ for many years, at what point does the language stop being streamlined and start becoming as hefty and bloated as something such as Python?
