+ `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.
