Just a friendly note from my PHP user side:
We had 2 places where {} where used for accessing string.
Took me 10 seconds to remove those with the help of
the nice E_STRICT error. (filename, linenumber)

As far a code readability and obviousness goes, I doubt anybody would guess their way to the $str{5} syntax.
But you know without understanding of any context, that it's the 6th character of the string "$str". When you see $var[5], it could be the 6th character of a string, or an element of an array... and what about the value? You can't be sure that it's a string with length 1, it also could be another array, an object, a string with length 4711...
That increases complexity and decreases readability.
Your argument falls apart there. Try it:
$a = array("ab","cd","ef");
echo $a{2};
Guess what that prints? {} has nothing to do with strings. They are 100% equivalent to [] and as such add nothing to clarity.
