[fw-general] curly- instead of square-brackets?

[Jan Pieper]

Isn´t it better to use curly brackets ($foo{0}) instead of square 
brackets ($foo[0]) to get a single char of a string? I think it is a 
little bit confusing to use square brackets for char selection of a 
string because they are also used for arrays. (e.g. 
Zend_View_Abstract::__set())
