alt Hacker NewsWe know, the beginning of the article tells us his C code is APL-inspired. So many comments that just summarize the article on a surface level.

The beginning of the article talks about not learning APL--specifically mentions that he's not here to talk about APL--and proceeds into a wide-eyed dissection of the C without mentioning APL syntax again. It also doesn't, literally, say that the C is like APL; it says Arthur is an APL guy who writes weird C code. Another comment disagrees that this is APL style at all--which is it?? I think you could have given me more credit than this. I read the article and participated as best I could. I'm always happy to bump APL related articles so they get more visibility.

Yes, but... even if you know that it is APL inspired, that does not change the fact that this is not how you want to write C.
The C pre-processor is probably one of the most abused pieces of the C toolchain and I've had to clean up more than once after a 'clever' programmer left the premises and their colleagues had no idea of what they were looking at. Just don't. Keep it simple, and comment your intent, not what the code does. Use descriptive names. Avoid globally scoped data and functions with side effects.
That doesn't look smart and it won't make you look smart, but it is smart because the stuff you build will be reliable, predictable and maintainable.
