That is, the top level rule depends on a stop marker, such as "}", to terminate, and processing may stop before an EOF is reached.  The only time your grammar needs an  EOF is to consume tokens from such a stop marker to the end of file; I find that rare.

Not so. See the "Evaluator bailing out early?" thread for a counterexample.
