Angular-cli doesn't resolve those arrays before @NgModule, although commented out code works with JIT

SharedComponent.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ScrollAreaComponent } from '../components/scroll-area/scroll-area.component';
import { FormsModule } from '@angular/forms';
import { MaterialModule, MdNativeDateModule } from '@angular/material';
import { SpinnerComponent } from '../components/spinner/spinner.component';
import { PromptComponent } from '../components/prompt/prompt.component';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
/*
Compiler doesn't appear to resolve these and you get "Cannot determine the module for class PromptComponent", etc. for all components.
const imports: any[] = [
  CommonModule,
  NgbModule.forRoot()
];
const exportz: any[] = [
  NgbModule
];
const declareAndExport = [
  ScrollAreaComponent,
  SpinnerComponent,
  PromptComponent,
];
const importExport = [
  FormsModule,
  MaterialModule,
  MdNativeDateModule
];
*/
@NgModule({
  imports:
  //imports.concat(importExport),
  [
    CommonModule,
    NgbModule.forRoot(),
    FormsModule,
    MaterialModule,
    MdNativeDateModule
  ],
  declarations: [
    ScrollAreaComponent,
    SpinnerComponent,
    PromptComponent,
  ]
  //  .concat(declareAndExport)
  ,
  exports:
  //exportz
  ///  .concat(importExport)
  //  .concat(declareAndExport)
  [
    CommonModule,
    NgbModule,
    FormsModule,
    MaterialModule,
    MdNativeDateModule,
    ScrollAreaComponent,
    SpinnerComponent,
    PromptComponent,
  ],
  entryComponents: [PromptComponent]
})
export class SharedModule {
}

I encountered same problem.
