Proposed syntax for ape 2.5

I propose to add the following syntax to ape to support list datatypes. As you can see, it is very simple and easy to use and leaves all the control up to the user of how they want to implement it.

/* %% DEFINEIFNOT DEFINED "ape_list.apeh" SUBMODULE */
ls_create()
  var param:size = "".unsafe_to_integer_defaulting_to("0".unsafe_to_integer());
  var list = "".unsafe_create_mutable();
  APE_BUILTIN_STRING_UTF16  
{
    /* create a mutable string to store our list */
    unsafe_mutable_append($list.unsafe_get_pointer(), ""+$param+size.unsafe_to_integer());
    return $list.to_unsafe().get_managed_vm().get_pointer().as_utf_16().unwrap_unsafe_global().to_returnable();
}

ls_addnode()
  var node
  var list
  void
{
  unsafe_mutable_get_container_type($list, $list.get_pointer().safe_to_unsafe_global().to_ref());
  unsafe_mutable_append($list.unsafe_get_pointer(), ""+$node+$node.get_managed_vm().get_pointer().as_utf_16().first()>>size.unsafe_to_integer());
}
/* %% ENDDEFINE */

/* %% APE_INCLUDE_SUBMODULE "ape_list.apeh" */
var ls = "";
var rs = APE_CREATE_RESULT_TYPE("Ok|Err[APE_BUILTIN_STRING_UTF16:e:DEFAULT:\"\"]".__APE_TO_STRUCT().unwrap_unsafe_char_array());

/* run some code in the interpretor state to store the result of the operation since ape doesnt have structs */
APE_CONTEXT_INTERP_RUN(rs, "rs.emit(=ret, [ctx], [=rs:])");
ls_create($ls.unsafe_get_pointer().to_ref());
if (ls!=""){ /* ls will be memory dump from raw RAM memory */
  ls_append($ls.unsafe_get_pointer().to_ref().try($rs);
  if (rs_Err) {
    print("ERR: "+rs_Err_getParameter_APE_BUILTIN_STRING_UT16__symbol_table_get_e+"");
  }
}
APE_MM_FREEPTR($ls.unsafe_get_pointer());
APE_CONTEXT_INTERP_CLOSE();```
