That's the problem - also grep does not know if [] is used for

That's true. But what about "reducing complexity"?
Don't you think it's useful to allow a convention like {} for
strings and [] for arrays, so you can be sure what $str{1} means
without looking at any context?No.
Why not? If users demand it, why not allow them that facility?
I think the visual difference between [] for arrays and {} for string access is a superb feature of PHP. (Personally, I'd like to see it extended to something like $s{2:5} or $s{2,3} for longer substrings, but I've proposed that before and been shot down so I won't mention it ;)
If {} for string access goes away, I won't be converting to [] becasue I think a visual difference is vital -- so all my $s{$x} will be turned into substr($s, $x, 1).
Cheers!
