ImportCall :
import( AssignmentExpression )
1. Let referencingScriptOrModule be ! GetActiveScriptOrModule().
2. Assert: referencingScriptOrModule is a Script Record or Module Record (i.e. is not null).
3. Let argRef be the result of evaluating AssignmentExpression.
4. Let specifier be ? GetValue(argRef).
5. Let promiseCapability be ! NewPromiseCapability(%Promise%).
6. Let specifierString be ToString(specifier).
7. IfAbruptRejectPromise(specifierString, promiseCapability).
8. Perform ! HostImportModuleDynamically(referencingScriptOrModule, specifierString, promiseCapability).
9. Return promiseCapability.[[Promise]].
GetBindingValue (N, S)
[...]
3. If the binding for N is an indirect binding, then
a. Let M and N2 be the indirection values provided when this binding for
N was created.
b. Let targetEnv be M.[[Environment]].
c. If targetEnv is undefined, throw a ReferenceError exception.
d. Let targetER be targetEnv's EnvironmentRecord.
e. Return ? targetER.GetBindingValue(N2, S).
