A "bare" function name (without parens) is the address of the function,
which can be converted to an int, long, etc.
So the "rank" identifier can validly refer to the function in this context.
This is no different than C with respect to typing rules:
$ cat foo.c
#include <stdio.h>
int main(void) { printf("%ld\n", main); }
$ gcc -o foo foo.c
$ ./foo
