There are cases where we've got a reference to a TemplateRef and would like to use it to stamp out live HTML fragments. Currently it can be easily done from the JS side (viewContainerRef.createEmbeddedView(tplRef)) but this issue is about creating a directive that would allow us to do this "inserting" from a template.

A "workish" example of such directive:

@Directive({
    selector: 'ng-insert-tpl'
})
export class NgInsertTpl {
    constructor(private _viewContainerRef: ViewContainerRef) {
    }

    @Input() set template(tplRef: TemplateRef) {
        this._viewContainerRef.createEmbeddedView(tplRef);
    }
}

Naming things is hard so ng-insert-tpl is definitively up to debate.

This is part of #7546 (comment), it could be used in action like so: http://plnkr.co/edit/sleVVrgqo66JN9G48yyj?p=preview
