Re: PHP 5.1

Hi Zeev, You're absolutely right.. How awful of me that I didn't see this coming. Honestly, what's the point of having an ifsetor() in PHP, when people can obviously write it themselves? Everybody wants a slighty different implementation of an ifsetor(), ifnotemptyor(), coalesce(), etc... Why are people wasting their breath on this? I figured it would be a good addition to PHP at first, but seeing as everyone could write this in PHP themselves, I really don't get the point. Maybe it's the case that a lot of pro-ifsetor() people, are unaware (like I was) of the fact that one really could implement a decent ifsetor() themselves?
