The braces make it clear that @$ is not a special sigil; that it's still an array with something going on inside. It also enhances readability on long or compound (deep hash access, for example) variable names. IIRC, there used to be a case where it further was necessary to disambiguate the resolution of variables but I'm not sure about that or if it's still true.
