Detailed Description

Represents a 'co_return' statement in the C++ Coroutines TS.

This statament models the initialization of the coroutine promise (encapsulating the eventual notional return value) from an expression (or braced-init-list), followed by termination of the coroutine.

This initialization is modeled by the evaluation of the operand followed by a call to one of: <promise>.return_value(<operand>) <promise>.return_void() which we name the "promise call".
