Yes. Actually the algo in members()  defines and runs over multiline 
slices, that shortens a lot the number of iterations in the explicit 
loop (in order to maximize the vectorized (and so faster) processing of 
the bloc/slice), but is more complex to implement.
Since using single lines in the loop already saves a lot of time for 
your case, and is enough, simplicity is smarter.
