But seriously, HOW MUCH would it slow down? Are we talking 5% or 50%? Considering the speed increase php4 has over php3, I wouldn't mind
loosing 5% to provide additional stability. If it were significantly
higher, then rather than saying something like 'dont do it and it wont
crash', provide the explanation that protecting against such a crash
would slow down php so much that it isn't worth it, so you just have to
pay attention to your scripting.
I agree with Andi that there should be _no_ performance decrease (if not smaller than 0,01%) implementing a protection function for infinite recursion. That´s a very rare effect.
