Can a scanning operation be done within a conjunction? It seems that
backtracking into it does not produce the next result but begins the scanning
over again. And if the '?' scanning expression is put out of the conjunction,
the part that is left in it sets the position back to where it was before
scanning when the other expressions in the conjunction are evaluated.
