Is there something like a consuming take?

Doesn't look like what I'm looking for, as it is exactly the same 
I allready found.

Maybe I need to explain, what I dislike with this approach: 
take() calls popFront n times and drop() calls popFront another n 
times giving a total of 2n times (depending on the underlying 
range, this might cause lot's of calulcations be done twice. The 
first version with the foreach loop calls popFront only n times.
