Hello,

I realised today I made a wrong assumption with iPojo. I thought that if I 
used a factory to create an instance, that I could be 100% sure that the 
instance was going to be valid because (I thought) that if the instance 
was missing dependencies, the factory itself would be invalid. That is not 
the case, however. So I am wondering, why is this the case? Now i will 
have to check after any instance creation if the instance is valid but I'm 
not sure why.

What is the use case where you would want a factory to allow you to create 
invalid instances? why isn't the state of the factory tied to the state of 
the instances it creates so that if a factory is not capable of creating 
valid instances, it itself is invalid?

Thank you for any insights
