Hi Andi Gutmans, you wrote: I don't mind undeprecating it while I continue to digest the whole instanceof thread and look at real-world examples... After all I think there's more hidden behind than just your argument about the generic way...? Why are you defending this broken bridge that hard?

Nothing hidden. I just don't think it's broken. I don't think it'll be terrible to change and I will look into it (actually already have). I do think that people here missed the point though. If your code really requires this functionality then I think there's a problem in most cases. I think for most people in favor it was more a philosophical argument then one backed with massive real world usage... About PEAR, I don't know the code and excuse me if I don't trust your stats :) Andi

You're saying that PHP shouldn't be that dynamic regarding this issue, so why does it try do dynamically load a class within instanceof (which is needless *in every case* anyway)? I think PEAR qualifies as a "real-world" example and there is_a() is used about 680 times, now if that would be instanceof and we assume 10% to check for a non-existing class, it'd bail out at about 70 instances.
