You're right that using eval() slows.. But using the _init() function as
you suggested is actually tricking in a way you move the constructor
params to another function, but the initialization params should be sent
to the constructor!

I guess that it would be better if PHP will add a possibility to
construct a dynamic class with variant number of params... ;-)
