Where do you get this percentage?
Do a fgrep -rn is_a\( in PEAR for example. And please no stupid
comments (not you Andi the evil other ;)).
There is plenty of good reasons to do this check.
You are missing my point. I didn't say people don't use is_a(). There is a
lot of PHP 4 compatible code which you'll find is_a() in. I said the amount
of instances where you actually require the proposed behavior is neglgible.
It happens with plug-in architectures which generally speaking, tend to
also use Reflection functions (incl. class_exists, function_eixsts, etc.).

These are _compiled_, _linked_ languages. The simple fact that you
cannot compile your sources explain the tricks. PHP is (should I
say was?) mostly a dynamic and scripting language.
Being a dynamically typed language doesn't mean everything should be
dynamic. Does it mean we have to allow adding PPP properties/methods on the
fly, allow for dynamic type hints ($ClassName $obj), and so on? I'm not
expecting you to answer these questions but being dynamically typed doesn't
mean the whole language is dynamic. That doesn't mean you can't/shouldn't
argue your point, but I think this is a bad reason.

What is important to me is that "you" deprecate things without
acceptable alternatives.
Did I deprecate it? And yes, as I mentioned there is an acceptable
alternative, although it seems it's not acceptable to you. I can't argue
that point as it's how you feel.

Wrong....
We must be looking at completely different applications.
