Return the stat vector for FILENAME in DIRENT. If the stat fails (for example, if the file has gone missing since the dirent was populated) then #f is returned. Stat vectors are cached upon first access and subsequent stats are returned from cache.

    (and (stat-regular-file? s)    ;; or, (pf:regular-file? de fn)
         (> (stat-size s) 0))))
