code: public final Parser<List<T>> sepEndBy1(final Parser<?> delim) {
      return next(first ->
          new DelimitedParser<T>(this, delim, ListFactory.arrayListFactoryWithFirstElement(first)));
    }
docs: A {@link Parser} that runs {@code this} for 1 ore more times separated and optionally terminated by {@code
  delim}. For example: {@code "foo;foo;foo"} and {@code "foo;foo;"} both matches {@code foo.sepEndBy1(semicolon)}.
  
  <p>The return values are collected in a {@link List}.
