Or literally a part of the self, which is what the OP was getting at I think. And there is plenty of that in the software world. "I'm a Rubyist", "I'm a Pythonista", "A rustacean" and so on. There is plenty of identity ridiculousness. I've been a C programmer but I've also been a basic programmer an assembly language programmer, a PHP programmer, a FORTH programmer and a whole list of others. To me that collapses to "I'm a programmer" (even if the sage advice on HN by the gurus is to never call yourself a programmer I'm more than happy to do so). It defines what I do, not what or who I am, and it only defines a very small part of what I do. That's one reason why I can't stand the us-vs-them mentality that some programming languages seem to install in their practitioners.
I think it’s because C++ programmers tend to define themselves by the domain they work in. Game developer, embedded systems engineer, firmware developer, etc.
I feel like it implies "it's harder to make a word out of 'C++' than it is for things that already naturally evolved as words people say like 'Ruby', 'Python', or 'Rust'".
