Oh, I see. It's about *protecting* the main script's positional
parameters from the sourced script. In that case, the function wrapper
seems to be a reasonable solution. Just replace the set -- with shift as
others have already suggested. And add a comment describing why you're
doing this, so old people like me won't be confused by a function that
appears to have no purpose (in 99% of cases).
