Your example sort of confuses me. How do you know what NoOp returns?

Even though NoOp could theoretically take arguments, the point (IMHO) of
NoOp is to do nothing. If it did return something, why wouldn't it always
return the same thing?

Also, doesn't the "?3"  in thesecond expression change things? Or is that
outside the scope of what you're asking?
