The one other example I know that morphs the language to that extent and to the detriment of readability by C programmers is the J interpreter[1,2]. But, once again, nobody (that I’ve read) claims it’s good or clear C. (Good C for those who speak J, maybe; I wouldn’t know.) For a way to morph C syntax that does make things better, see libmill[3].

I started a project a couple months ago. I’m slowly porting that code base, the J source code to C++ 20. And yeah, I think there should be a name for these types of code bases, because it’s not C, it’s like a macro variant of C, where it’s a CDSL,

where 80% of your “library” is macros. I did a search, there’s 10,000 macros in the source code, and those macros are used like functions.
