In simple [.identifier] expressions it's not a problem. I was foreseeing more complex expressions, as I suggested earlier.
Here, also with the context would fully disambiguate between other uses so I do not think there is any issue with using this syntax. '$' is much more problematic as people use it in identifiers, '@' may cause confusion with objective C.

'$' is too bad. '@' is confusing. I think I'll keep the '.' for now then, and assume that there's a high possibility that we'll never have complex expressions with it.
