+  `let await` does not permit ASI in between, as `await` is a BindingIdentifier
+info: |
+  `await` 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 `await`,
+  so a subsequent `0` where `=` was expected is a syntax error.
