Parse error for quoted export/import names

// e.mjs
const a = 'print me';
export { a as "dove" };

// i.mjs
import { "dove" as b } from './e.mjs';
console.log(b);

"dove" is the quoted name, and this code works (i.mjs prints print me).

Spec reference: ModuleExportName can be StringLiteral.

However, compiler can't parse that:

e.mjs:3:14: ERROR - [JSC_PARSE_ERROR] Parse error. 'identifier' expected
  3| export { a as "dove" };
                   ^

i.mjs:2:9: ERROR - [JSC_PARSE_ERROR] Parse error. '}' expected
  2| import { "dove" as b } from './e.mjs';
              ^
