  `let yield` does not permit ASI in between, as `yield` is a BindingIdentifier
info: |
  `yield` is a perfectly cromulent binding name in any context grammatically, just
  prohibited by static semantics in some contexts.  Therefore ASI can never apply
  between `let` (where a LexicalDeclaration is permitted) and `yield`,
  so a subsequent `0` where `=` was expected is a syntax error.

  phase: early
