Well, I actually didn't ask 'what's the point of foreach is if it's 
slower' :) I just wanted to find out if it's really as far as it can 
get, or is it simply not polished yet.

Nevertheless, I agree that seeing some kind of roadmap would be nice, 
especially now when D2 is shaped to certain extent and someone would 
consider starting mean projects with it.
