>>27 thats not "unreadable", its code for public consumption.
I can write code with shorter variables and more macros.
Indentation also not used at all. Compare this with https://raw.githubusercontent.com/FrozenVoid/C-techniques/master/scope.c
#include "Util/void.h"
int g=4,l=50;
#define prscope(s) print(s,g,l)
void f(char*s){prscope(s);}
#define ex(s) ({prscope(s);})
void of(char*s){prscope(s);}
void f2(char* scope){int g=2000,l=6000;
void f3(char*s){prscope(s);};f3(scope);//2000,6000
atype fptr=of;fptr("\nGlobals again:");
