I use this construction quite a lot:

        var elm = evt.element();
        if(elm.tagName.toString().toLowerCase() != 'td') elm = elm.up('td');

whenever I am constructing a rollover listener, since it works around  
the whole issue with mouseover / out events firing whenever you move  
over a child of the element you're trying to observe. Is there a  
simpler way to do this, a more Prototype-y way, that is? I've had a  
look around the API, and I also had a Google, but the former didn't  
turn up anything useful and the latter turned up every commit message  
from every project that includes Prototype.

Thanks in advance,

Walter
