Re: [RFC] Generalize support of negative string offsets

Hi! > The only concern I have is that support of negative indexing will break > symmetry with (proper) arrays, where we cannot support negative indexing. 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"]. > However this is unlikely to be a significant issue.

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. -- Stas Malyshev smalyshev@gmail.com
