Hi!

    static $a = -'abc'; // 0
    static $b = +'abc'; // abc
    $c = +'abc'; // 0

}

We could get into trouble here. Imagine: static $a = -'12.8'; This should be -12.8, but what if locale changes and . is no longer decimal separator? Moreover, what if locale changes between compile and runtime? We get entirely different code now.

Well, I don't know if it can be tossed in quickly at this time, but there ya go since I think it's pretty basic! ;^)

I think it's not the feature that can be "tossed in quickly" - it can have some obscure side effects, as I described in my later emails. -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
