Thanks for your interesting message. I agree with you that one needs to simplify the code as far as possible. In most situations where I use loops, it is because at each index, I am computing some new variables that need to be stored (for example in a time integration routine). In this case, I can't get rid of the loop construct because of the "varying data".
