I think that most problematic for prefix notation are not arithmetic operations, but field accessors.
In C you have a->b->c->d, in Lisp it would be (d (c (b a))), which makes you to jump to the center and read it from the inside-out.
The direct translation of the Lisp expression you shared to C would be: d(c(b(a))), which just like the Lisp expression, evaluates from the middle out. Both are fine to read from left to right though.
Not really. -> looks like binary infix operator, but it is really an unary postfix operator (parametrized by field). Because field itself is not a first-class entity in C.
#include <stdio.h>
#include <stdlib.h>
struct foo {
int a;
};
int main() {
struct foo *f = malloc(sizeof(struct foo));
f->a = 5;
printf("%d\n", f->b);
free(f);
return 0;
}
