I think that was the main source of objections to this proposal in the
past. However, as one might say, string offsets are already not
symmetrical to array offsets - e.g. you can do $array["foo"] but not
$string["foo"].

I think it may be a good idea to start recommending using {} for string
offsets and [] for arrays. While both syntaxes may work for strings, the
intent (and expected handling of negatives, in this case) is much
clearer when different syntax is used.
