Within {{#each}} clause, how do I find my element's sequential number?

I would like to to do something like this:

  {{#each authors}}
    <li> {{row_number}}.  {{name}} </li>
  {{/each}}

Where row_number starts with 0.

Conventional approaches don't seem to work because of the reactivity (different rows updated at different times).

This will return an author, not the author's number in the list. – Irina Rapoport Apr 19 '15 at 21:29

No it won't. It will return the row number if use map as in the posted link – Eliezer Steinbock Apr 19 '15 at 22:40
I get it now. Yup, it should work. Thank you. Although some have complained of performance implications. Do you think there would be any? – Irina Rapoport Apr 19 '15 at 23:27
No, not on the client unless you are listing tens thousands of authors at once... but then this helper won't be your main issue. I'm marking this as a duplicate. – David Weldon Apr 19 '15 at 23:28
