A-Compiler:适用于我的编程语言的小型简单编译器

A编译器 var fns := {add_one, mul_two, square}; fn add_one(a: u8) -> u8 { std.printf("adding one: %u8\n", a); return a + 1; } fn mul_two(a: u8) -> u8 { std.printf("mul by two: %u8\n", a); return a * 2; } fn square(a: u8) -> u8 { std.printf("squaring: %u8\n", a); return a * a; } fn main() { var x := 0; var a: u8 = 4; while x < 3 { a = fns[x](a); x++;
