string concatenation with property binding in angular2 : <p>in Angular 2 we have several way to create property bindings in templates.
I could do something like this:</p>

<pre><code>&lt;li *ngFor="#course of courses; #i = index" id="someselector-{{i}}"&gt;{{course}}&lt;/li&gt;
</code></pre>

<p>Is it possible to obtain the same result using the square brakets syntax?</p>

<pre><code>&lt;li *ngFor="#course of courses; #i = index" [id]="someselector-i"&gt;{{course}}&lt;/li&gt;
                                            ^^^^^^^
                                  how create string concatenation?
</code></pre>

<p>Thanks,
G.</p>
