in Angular 2 we have several way to create property bindings in templates.
I could do something like this:

<li *ngFor=#course of courses; #i = index id=someselector-{{i}}>{{course}}</li>

Is it possible to obtain the same result using the square brakets syntax?

<li *ngFor=#course of courses; #i = index [id]=someselector-i>{{course}}</li>

                                            ^^^^^^^

                                  how create string concatenation?

Thanks,
G.
