• Support by-reference semantics for for value_ref, i in &some_array and for key, value_ref in &some_map
• Allow map indices to be references &m[key] and return a valid pointer if exists otherwise nil
• Allow referencing a compound literal &Foo{}
• Slice literals will use stack memory within a procedure and global memory in a global scope
