Yeah, that would need to be solved. In Ruby it works like this:

[1, 2, 3, 4].each do |i|
   if i == 2
     return
   end
end

Results in:

LocalJumpError: unexpected return

If you instead wrap it in method you can return from the each-block. So 
in Ruby it behaves just like having a "return" in a plain for-loop and 
not in a delegate. It would basically force a return in the "each" method.
