Porting python's `for`/`else` to C with no `setjmp`.

py_else.c

#include <stdio.h>

#define py_for(...) for(int loop_flag = 2, break_called = 0; loop_flag && !break_called; --loop_flag)if((loop_flag == 2) && !break_called)for(__VA_ARGS__, break_called = 0)if((break_called = 1), 0){}else
#define py_whl(...) py_for(;__VA_ARGS__;(void)0)

int main(){
	py_for(int i = 0; i < 5; ++i){
		printf("%d\n", i);
	}else{
		puts("egg");
	}
}

Your move, @Oderjunkie.
