@lcamtuf The more I stare at this code, the more I think I actually hate you. I mean, in a good way, but still. 😉

@lcamtuf The second example is clear enough. But the first, uh, gcc's hand-crafted parser clowns the standard committee yet again.
💯 for "using" the function and avoiding the warning.

@lcamtuf subtitle of your book "C for perl coders"? ;)
And as a bonus for the first 42 copies you get a little spray bottle of bleach to apply gently to your eyes? ;)

@lcamtuf Can I get a printed version ... not sure whether I want to burn it or frame it. 😂
Reminds me of Scala workshop I attended. The instructur started with showing off how beautiful Scala code could be and without commenting on it at all, the code on his slides just got progressively more uggly until it reached a similar level of cursed. 😬

@lcamtuf oh god i spent like 5 minutes trying to figure out where this syntax to override function symbols was defined before realizing it wasn't different from the "normal" syntax
