one way data binding by default

Use one way data binding only and by default as angular 1.5 uses

https://github.com/angular/angular.js/commit/4ac23c0ac59c269d65b7f78efec75d060121bd18#diff-a732922b631efed1b9f33a24082ae0dbL3037

angular doesn’t copies those parent values, so if we have object and modify a property it will be mutated on parent, which is not very convenient. We wanna push best practices and stay immutable, so we will copy @Input props via angular.copy.

Although we should keep fallback for people which really need 2 way binding:

// one way only
@Component({ 
  selector: 'hero', 
  template:`hello`
})
class HeroComponent{
  @Input() name: string;
  @Input() skills: string[];
}

// two-way fallback via alias only
@Component({ 
  selector: 'hero', 
  template:`hello`
})
class HeroComponent{
  @Input('=') name: string;
  @Input('=') skills: string[];
}

yeah you’re right, so in your particular scenario just don’t use OnPush and use ChangeDetectorRef.

I will explore possibilities if it’s possible to tweak it to be more aligned with Angular 2, but that’s not the primary focus right now ( after ngMetadata 2.0 will be released )

Anyway, thanks for brilliant brainstorming ! These kind of conversations are golden!
