1. It manages memory through deterministic ownership rules and optional arena allocation. Pointers never outlive the allocator that created them, and the compiler performs lifetime checks to prevent use-after-free or double-free errors.

2. Axe does not use C++-style RAII. It employs deterministic cleanup through defer, which allows resources to be released predictably. Also, objects allocated inside an arena are freed as a group when the corresponding arena is destroyed.

3. Not yet. There is an overload system currently:

  overload println(x: generic) {
      string => print_str;
      char*  => println_chrptr;
      i32    => println_i32;
      char   => println_char;
  }(x);
