    ImportCall : import ( AssignmentExpression )

    1. Let referencingScriptOrModule be ! GetActiveScriptOrModule().
    2. Let argRef be the result of evaluating AssignmentExpression.
    3. Let specifier be ? GetValue(argRef).
    4. Let promiseCapability be ! NewPromiseCapability(%Promise%).
    5. Let specifierString be ToString(specifier).
    6. IfAbruptRejectPromise(specifierString, promiseCapability).
    7. Perform ! HostImportModuleDynamically(referencingScriptOrModule, specifierString, promiseCapability).
    8. Return promiseCapability.[[Promise]].
