Not really, since instructions don't "do anything" anyway - they only
compute values.
If you are in the IO monad then "return ()" is the do nothing.
I need this answer. This is my case. Thanks you very much.
In the function world, "id" is the do nothing.
In recursive list processing, then something like [] is probably the
"base case" in a recursive function, so stops the recursivity.
If you give a more concrete example, then maybe we can give you a better answer.
Thanks
Neil
