True, nevertheless for-in works fine on MSIE7 and FF2. Isn't the NodeList
enumerated? Why would for work and for-in not?
It seems to me like the suggested loop, which is actually the exact same thing
I did to fix it with Safari, should behave the same way as a for-in, while the
for-in has a more compact syntax and is more readable, in this case.
