Class/trait/interface "{ClassName}" was added in the global namespace.

HI guys,

I'm getting many times this kind of error:
Class/trait/interface "{ClassName}" was added in the global namespace.

I don't undestand why this situation should throws an error in PHP7; at lease, I would expect a warning!

Thanks

Hello @fanphp. I'm not sure I understand your problem. Can you provide a snippet of code that can be used to reproduce the issue?
