^

Use ^ for address, * for value1 2, ! for ownership
Jai does not use & for references; using can provide that functionality 3

N :: 10;

Entity :: struct {
   serial_number : int;
}

value : Entity;     // type declared as Entity
values : [N] float; // type declared as N-long array of floats

pointer : ^Entity; // type declared as address of an Entity
pointer = ^value;  // assignment as address of Entity named 'value'
pointers : [N] ^Entity // type declared as N-long array of addresses of Entities

pointer := ^value; // get a pointer to a value's memory address
value := *pointer; // get a value by dereferencing a pointer


owned : node *! = null;
other : node *  = *graph.node;

  1. for pointers, use Pascal-style pointy hat (^) instead of ampersand (&). still use star (*) to dereference a pointer.

  2. star (*) brings us toward the value, and hat (^) brings us away from the value.

  3. references in C++ are just pointers with a different syntax and different defaults, so I would rather have a way to have one thing.
