    14.7 Async Arrow Function Definitions

    AsyncArrowFunction :
      ...
      CoverCallExpressionAndAsyncArrowHead => AsyncConciseBody

    AsyncConciseBody :
      { AsyncFunctionBody }

    ...

    Supplemental Syntax

    When processing an instance of the production AsyncArrowFunction :
    CoverCallExpressionAndAsyncArrowHead => AsyncConciseBody the interpretation of
    CoverCallExpressionAndAsyncArrowHead is refined using the following grammar:

    AsyncArrowHead :
      async ArrowFormalParameters


    Runtime Semantics: IteratorBindingInitialization
    FormalParameter : BindingElement

    1. Return the result of performing IteratorBindingInitialization for BindingElement with arguments iteratorRecord and environment.
