| `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. |
