Re: Reflexive & Reciprocal Marked on the Verb

I asked my francophone friends some time ago, they gave me the following:

Ils se regardent.
They look at each other.

Ils se regardent dans le miroir.
They look at themselves (!) in the mirror.

I suppose you could disambiguate to some extent by using "l'un l'autre":

Ils (se?) regardent l'un l'autre.
They look at each other.

But maybe a real francophone can elaborate on this.
