Yes, but that requires the compiler to generate the return value »glue«

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.
