As far as I remember, the problems were due to new objects. 

The namespace issue is not too severe to call for urgency. It will be good, if 
a solution can help having a clean code.

A slight annoying problem with classes whould be that hooks, if
translated directly, will become arrays, as opposed to simple strings.
This is required for method callbacks.

On the plus side, we can factor in a load per need, triggered on error,
for example class not found. Which might reduce the memory use.
